performance/stat-prefetch: don't check whether previous lookups have been failed in sp_process_inode_ctx.
We need this patch for following reasons:
1. The inode used in the successful lookup call may not be the one passed to
fops operating on path. This may happen, if revalidate of inode is failed,
but the lookup itself succeeds (in case of reavalidate failures, fuse
sends a fresh lookup using new inode) and since inode_link, if there is an
inode already associated with a path retains it.
2. Only fops that "wait" in stat-prefetch on a lookup which is already in
progress, need to check for the result of the lookup they are waiting on,
before resuming and sp_process_inode_ctx is _not_ used in such contexts.

performance/stat-prefetch: make lookup to wait for the completion of another lookup on same path if one is in progress.
- If current lookup (2) does not wait for completion of the lookup (1) which
is in progress, there can be a race condition where (2) completes ahead of
(1) and resuming all the waiting operations in the queue. When (1) returns,
the original operation (eg., stat, chmod etc) might've already unwound and
hence the frame would've been destroyed.

performance/stat-prefetch: don't free the cache in readdir if the offset is not the expected one.
- cache creation is expensive operation. Also, cache will be freed in
releasedir. Hence, just remove all entries from cache without freeing
the cache. However this is not entirely true, since sp_cache_remove_entry
frees the old table and reinitializes a new table if all entries are being
removed. When rbtree based hash table provides an interface to remove all
the entries, sp_cache_remove_entry should be modified not to destroy the
table.
- this patch also fixes a race condition wherein the cache being used in
lookup getting freed in readdir if the offset is not equal to expected
offset.

- when listen-host is not specified and there are are no interfaces having
adresses belonging to the address-family specified, listen at 0.0.0.0/::0.
- this patch is necessary since with AI_ADDRCONFIG, getaddrinfo fails if there
are no active interfaces for the address family specified and when
listen-host is specified we still want the functionality provided with
usage of AI_ADDRCONFIG.

cluster/afr: Prevent spurious entry self-heal.
If the initial lookup shows that 'pending' is positive, then
self-heal will hold a lock and do a lookup again. This lookup
might show that 'pending' is zero everywhere. However, entry
self-heal used to consider this as a case of 'no sources' and
try to merge the directories. This patch checks for that case
and does not do the merge.

performance/stat-prefetch: Add support code to implement lookup-behind.
- change sp_lookup and sp_lookup_cbk to support sending lookups when needed.
lookups might need to be sent in fops like open, chmod, chown etc which
operate on a path, since the actual lookup sent to stat-prefetch by its
parent xlators is not propagated down the xlator tree if the path is
cached.

instead of in sp_lookup itself. This would reduce network traffic

performance/stat-prefetch: optimizations to sp_lookup.
- if stat cache cannot be found for a path in its parent inode and the path
is a directory, we can get the cache from the inode corresponding to path
and look for "." in that cache.

performance/stat-prefetch: change behaviour of sp_lookup when xattr_req is not NULL.
- if the xattr_req is empty (fuse just creates an empty dictionary and
sends along lookup) we can still use the cache prefetched during readdir,

performance/stat-prefetch: fix memory leaks
- sp_cache_get_inode uses fd_lookup which internally increases the refcount of
fd by 1. This needs to be unrefed once we get the cache.
- for directories, stat is stored in the inode context in sp_lookup_cbk.
but, while doing so, no check was being done for the presence of context
in inode, resulting in leak of memory equal to sizeof (struct stat) when
multiple lookups happened on the directory. stat was needed to serve the
postparent member during lookup. postparent stat is needed only in releases
having NFS related changes and hence removing code present to get
postparent.
- path constructed in sp_readdir was not freed.

This patch cleans up the umount and fini paths in preparation
to support waiting for unwind of all pending call frames.
Two misc fixes are:
1. Fix to avoid deadlock in _libgf_umount by
using _libgf_vmp_search_entry instead of
libgf_vmp_search_exact_entry since the latter tries to take a
lock already help by _libgf_umount.
2. Avoid a crash in _libgf_umount by deleting the vmp
entry from the list before it gets freed.

(for writes, both stub and request are destroyed when refcount becomes 0,

unwind requests the request is first destroyed before resuming the stub).

performance/write-behind: add option "enable-trickling-writes".
- With this option enabled, writes are stack-wound even though not enough
data is aggregated, provided there are no write-requests which are
stack-wound but reply is yet to come. The reason behind this option
is to make use of the network, which is relatively free (with no writes
or replies in transit). However, with non-standard block-sizes of writes
the performance can actually degrade. Hence making this configurable.

performance/write-behind: fine-tune logic of wb_mark_winds
- remove wb_mark_wind_aggregegate_size_aware, since wb_mark_wind_all does
the same work (with check for whether current aggregated data size is
greater than the configured limit before calling it). Moreover,
wb_mark_wind_aggregate_size_aware called __wb_get_aggregate_size
redundantly, thereby reducing the performance, since for small
sized large number of writes, traversing the list of requests takes
significant amount of time.

client-protocol: fix race-condition encountered while accessing fdctx
- In protocol/client, fdctx is accessed by two sets of procedures,
protocol_client_mark_fd_bad falls in one set whereas the other set consists of
all fops which receive fd as an argument. The way these fdctxs are got is
different in these two sets. While in the former set, fdctx is accessed
through conf->saved_fds, which is a list of fdctxs of fds representing
opened/created files. In the latter set, fdctxs are got directly from fd
through fd_ctx_get(). Now there can be race conditions between two threads
executing one procedure from these two sets. As an example let us consider
following scenario:
A flush operation is timed out and polling thread executing
protocol_client_mark_fd_bad, fuse thread executing client_release. This can
happen because, immediately a reply for flush is written to fuse, a release on
the same fd can be sent to glusterfs and the polling thread still might be
doing cleanup. Consider following set of events:
1. fuse thread does fd_ctx_get (fd).
2. polling thread gets the same fdctx but through conf->saved_fds.
3. Now both threads go ahead and does list_del (fdctx) and eventually free
fdctx.
In other situations the same set events might occur and the threads
executing fops other than flush in the second set might be accessing a
fdctx freed in protocol_client_mark_fd_bad.

booster: use __REDIRECT macro to prevent creat being renamed to creat64.
- nm on libglusterfs-booster.so shows only creat64 defined but not creat. This
behavior is observed due to following reasons.
1. Booster is compiled with _FILE_OFFSET_BITS=64.
2. fcntl.h when included with _FILE_OFFSET_BITS=64 defined, renames all
occurences of creat to creat64 in the source code from the point of
#include <fcntl.h>.
fcntl.h should be included since booster.c uses many of the macros defined in
that header and glusterfs (booster in turn) has to be compiled with
_FILE_OFFSET_BITS=64 since glusterfs uses datatypes (off_t, stat etc) whose
sizes vary depending on whether this macro is defined or not. Basically, this
macro should be defined to provide portability across 32 and 64 bit
architectures.
The correct fix is to make glusterfs to use datatypes big enough to hold 64 bit
variants as well as 32 bit variants (like int64_t replacing off_t) and not to
define _FILE_OFFSET_BITS=64 at all.
As a temporary work around,
1. we can implement creat functionality in a function with different name, say
booster_false_creat
2. rename this function to creat using __REDIRECT macro. since this renaming
happens after renaming of creat to creat64 (from the first __REDIRECT macro
in fcntl.h), we will end up with creat symbol being defined in
libglusterfs-booster.so

2.0.6 patch for io-cache pattern-matched non-caching
Hello all,
here is a small feature patch. Its intention is to give the user more control
over the files performance/io-cache really caches. If the user knows exactly
which files should be cached and which shouldn't there is currently no way to
tell glusterfs _not_ to cache certain pattern. This patch allows you to
disable caching by setting the priority of a pattern to "0". If you do not
give any priority option it works just like before and caches everything.
Honestly I am not totally sure that disabling caching works the way we did it,
please comment.

libglusterfsclient: Sync access to VMP list on new entry addition
Some weeks back, I'd separated the big lock into vmplock and mountlock.
See commit 304e4274ca9b0339539581c5413e3339078c1182 in mainline.
At that time, we did not have a solution to the problem
of when to init the vmplist in a thread-safe manner, since
there was no lock to protect the vmplock specifically, and that
when libgf_vmp_map_ghandle was called inside glusterfs_mount
so the "lock" was already being held.
Now that we have separate mount and vmp locks, the
accesses can be synced correctly.

protocol/client: fixed registration of saved_fds
In client_open_cbk, client_opendir_cbk the list_add_tail macros were invoked with wrong
ordered arguments, causing the existing registered fd list to get unlinked from the
saved_fds list. The effects of this is far fetched - when transport disconnects, open
fds are no more marked bad as they are not reachable from the saved_fds list. After
reconnection, resumed access on this fd causes reference to invalid fds on the server.
It could appear in the form of 'unresolved fd' error, readdir happening on a file fd,
files reading from other files, etc.

When an fd_t is fd_create'd, we need to call fd_bind on it to

doing this so translators like write-behind were not able to order
path-based requests at all resulting in some fops like stat, which
could be issued after a writev, overtaking a previous writev which
is still being written-behind.

libglusterfsclient: Use iobufs for storing application write data
Till now we've been creating an iovec, storing references in it
to the application data and simply passing it on to the translator
tree. This means that the buffer being passed to the translators is
not at all associated with the memory ref'd by the iobref argument
to write fop. This is a problem when write-behind is a translator in
the tree since it assumes that the memory in the iovecs passed to
write fops is already refcounted by the iobref and so it simply copies
the address of the application data. The problem is that the application
can continue using this buffer, free it or over-write it destroying the
data that write-behind may write at a later time.
The solution involves copying the application's write buffer into
an iobuf which will be referred to by the iobref.

libglusterfsclient: Avoid overwrite of inode found through ino number
In libgf_client_loc_fill, there is a possibility that all
the ino, par and name are specified as non-NULL,non-zero args.
So if an inode is located in the itable using the ino and the
subsequent search for the inode using the par-ino and the file
name does not result in an inode being found, the current
code over-writes the inode that was found through the ino. The
correct behaviour is to stop further searches if inode
was already found using ino.

Add a random initial offset to the afr round robin index
This patch helps to distribute load across an afr cluster
when you have clients with the same access patterns, such
as in benchmarking or map-reduce. By randomly offsetting
the initial read_child_rr, clients should distribute reads
over the afr nodes on average.
A better solution could be to randomly shuffle the children
instead of chosing a different initial offset. This should
average the reads better across the nodes, but I'm not
sure if there are any other consequences to doing this.

cluster/afr - use different dictionaries for sending xattrop requests to each of the subvolume
- This patch fixes bug #29.
- Using separate copies of dictionaries also eliminates a potential bug in a
setup consisting of afr with a posix and client, each having io-threads on
top as children. Since posix_xattrop after performing required operations
on the xattr array passed in dictionary, sets the result at the same key
and in the same dictionary passed as input argument,
there can be race conditions where in the results of the operation on
posix-child can be sent to the other child as input argument for xattrop,
which ofcourse is wrong.

booster: Fix build problems with various libtool versions
We've been facing a problem on some test systems where the
booster.so is built by libtool as an executable rather than
a dynamically loadable library.
This problem is probably caused by it seeing a _init function in
the source. This is the name of the libc initiliazation
function so it could be the source of the problem.
In any case, ld-preloadable libraries must not have a function
called _init, instead they need to have __attribute ((constructor))
as the attribute for any and all functions the library wants
executed before the program's main(). Our earlier approach was
inherently problematic.
This commit also cleans up the booster Makefile for better
build behaviour. Credit: Harsha.

libglusterfsclient: Fix glusterfs_mount-vmp search deadlock
It is possible that the only translator in the libglusterfsclient
tree is the posix. In that case, inside gluster_init, the graph
init routines will need to call lstat on the posix subdirectory.
Since even the glusterfs stack is running over booster, those
calls will also first require vmp searching. BUT, the vmp lock
is the same as the mount lock that was already taken when we entered
glusterfs_mount, so a deadlock occurs.

booster: Another attempt to fix 32 and 64 bit interoperability
With this patch, we might have finally arrived at a solution
to the problem of function definition conflicts between
our functions and those of libc while over-riding the libc versions.
This commit defines functions which do not conflict with libc,
then it uses libc's own macro to redirect/rename these functions
to the actual sys call names in the binary.

booster: Add new booster-specific fd-table
The reason we need a booster specific fd-table is because
the libglusterfs fd-table has come to a point where it is

This conflicts with the way booster requires fds to be allocated
so this commit brings in a re-based version of a booster-specific
fd-table written by Raghu.

libglusterfsclient: Call inode_lookup to prevent pruning
This bug shows up while using unfs3 with replicate. The absence
of an inode_lookup on a looked-up/created inode results in it
getting pruned from the inode table. Consequently, a subsequent
lookup for the inode results in a different inode number being
returned by replicate. This breaks unfs3 because it tries to remember
the inode numbers returned by two different stat-family calls.

read-ahead: return with error code EBADF for fops on fds without file set in their context.
- since a successful open/create will _always_ set a pointer to ra_file_t in

- an example of operations on bad fd can be afr sending read on the child

io-cache: prevent frames from getting woken up while page is getting validated
1. A page will be put on the inode waitq if the 'freshness' has to be verified with an fstat()
2. while the fstat is in transit, other calls (like lookup) can update ioc_inode->tv, resetting the freshness (page still on inode waitq)
3. Another read request on the same page, after the updated freshness, will wake up the page frames neglecting the fact that the page is also waiting on the inode (waiting for the fstat completion)
4. once the page's frames are woken, the page becomes elegible for purging and can get destroyed for various reasons, leaving a destroyed page pointer in the inode's waitq
5. fstat returns and hits the destroyed page pointer causing a crash
The fix is to all together disable cache hits when any page of the same inode is under validation. The otherwise cache hit will now be subjected to the ongoing validation by getting queued to the inode waitq.

unify getdents count reduced to 512 (from 1024)
Thanks to Krishna <krishna (at) gluster.com> for pointing this out.
When a unify self-heal of large directory (directory with lot of entries)
is done, the getdents_cbk used to fail because of new limit of buffer size
(128KB). Noticed that earlier it used to streach upto 4MB, hence the value
1024 worked fine. By reducing it to 512, noticed, we can fit in well within
128KB limit, and hence unify self-heal goes through.

libglusterfsclient: Increase readdir block size
This improves the potential for pre-fetching a larger
number of dirents. Consider that, with 255 chars as the max
name length for each dirent, in the worst case scenario, where
we actually have files with such large names, we're not getting
more than 4 entries with the current block size of 1024.
Generally also, increasing the size to 4k provides us
with a higher chance that directories with low to medium
number of dirents will be pre-fetched in a single readdir fop.

libglusterfsclient: Add dirent pre-fetching and caching
The fop interface is such that we're able to extract more than
1 dirent in a readdir fop. This commit now enables libglusterfsclient
to read multiple entries on a glusterfs_readdir call. Once these
have been pre-fetched, they're cached till either glusterfs_closedir
,glusterfs_rewinddir or glusterfs_seekdir are called.
The current implementation is beneficial for sequential directory
reading and probably indifferent to applications that do a lot of seekdir
and rewinddir after opening the directory. This is because
both these calls result in dirent cache invalidation.

This commit changes mem-pool behaviour to return a directly usable

This is different from the previous behaviour where we're trying to fit

enough in terms of space but hopefully works better than not having any
mem-pool at all. Besides, I am not comfortable with mem-pool meta-data

mem-pool's data structure corruption.

libglusterfsclient: Wipe loc->ino in libgf_client_loc_wipe
Not cleaning up the ino member of a loc_t results in SIGABRT
in __inode_link because in some cases, the loc->ino is
different from loc->inode->ino. This happens especially in code
blocks which re-use a loc_t structure for pointing at different
inodes/files. For eg, if a loc_t has been assigned an inode and
an ino, and followed by a libgf_client_loc_wipe, then re-use of this
loc in say libgf_client_lookup results the SIGABRT because
libgf_client_lookup calls inode_link with the same loc_t. However,
this loc_t has just been assigned a new inode pointer but the ino
member still contains a previous inode's inode number. This difference
in inode numbers results in an assertion failure, so the SIGABRT.

libglusterfsclient: Refine readdir entry parsing logic
Here I am only refining the entry parsing code in order
to clarify the exit conditions from the loop. There were
a few workloads where this loop went infinite.

libglusterfsclient: Revert and re-do readdir conformance
This commit basically reverts the previous readdir conformance
patch I sent a few days back. That commit had a completely retarded
and broken way of maintaining per-directory dirent.
It was broken for two reasons:
1. Creating a wrapper structure around the directory's fd_t
only for storing a struct dirent is not clean enough. This commit
takes a better approach by storing the dirent in fd_t context.
This dirent is valid only if the fd_t refers to a directory.
2. That commit was made and tested under the assumption (..stupidity
is a better word..) that only opendir call is used for opening a
directory. That is not correct. Directories are also opened using the
open syscall. The point is, glusterfs_open returns an fd_t and so did
glusterfs_opendir. The previous patch actually changed opendir to
return a new wrapper structure. That is fine, if we go by the POSIX
definition of open and opendir because, they're both supposed to
return different types, an int and a DIR*. However, in
libglusterfsclient, all other code assumes that directory handles
corresponding to DIR* and file descriptors corresponding to int types
are the same type, resulting in use of the same locking and fd context
addition/extraction code. So a directory opened using opendir returned
a wrapper structure which went down into the libglusterfsclient stack
where some function called a lock on the handle assuming it was an
fd_t, since it is not and dereferencing of the supposed fd->inode->lock
results in a seg fault.
Obviously, this didnt show up till unfs3 used open() to open a
directory and not opendir.

transport shortcut b/w client and server
This patch makes the server pass back the transport pointer of the client. If the UUID matches, the client makes the local transport 'shortcut' with the remote transport (pointer received from server)
The shortcut simulates a socket queue. Instead of serialized messages going over the network and getting queued in the tcp socket queue, the messages get queued in a transport specific queue picked by a polling thread.

libglusterfsclient: Fix large directory reading bug
As of now, we use 1024 bytes as the buffer for reading directory
entries. If a directory as many files, then its possible that it does
not fit into this buffer, thereby requiring more than one call to
readdir. Now suppose the last bunch of directories fit more or less
exactly int the 1024 byte buffer. If this happens, the offset
extracted by the current logic(in libgf_client_readdir) never gets
updated beyond the first entry in this last block, because the last
block's first entry always remains same. This explanation is
convoluted, I know, but I too found out the hard way.

booster: Add VMP-based open support
In brief, when an open is called the VMP-based open is called first.
If that fails, the fallback is the Mount-Point Bypass(MBP) technique
which uses entended attributes to determine if the given
path is a gluster mount. If it is, it goes ahead to create a
glusterfsclient handle. All subsequent calls to this real mount point
get redirected to the glusterfsclient handle. The other fallback is
the actual open syscall on the local file system itself. This happens
when the absence of an extended attribute tells us that the path is
not even a glusterfs mount point.

booster: Integrate VMP-based mounting
This commit brings into booster the use of VMP based operations
which will allow users of booster to specifiy a VMP and use it
for transparently operating on a glusterfs client context.
Since applications are oblivious to booster's presence, because it is
LD_PRELOAD'ed, we need to specify the VMPs and the corresponding
options like volfile, logfile, loglevel, through a conf file.
By default, this conf file is the /etc/booster.conf. This can be
over-ridden through the GLFS_BOOSTER_CONF environment variable
for the application.
The format of the conf file is very simple for now. Each VMP is
described on a single line with space separated fields.
Format: <Virtual Mount Point> <volfile-path> <log-file> <log-level>
<log-level> takes the string representation of the usual glusterfs
log levels.

libglusterfsclient: Fix realpath operation
This commit does two things:
1. Ensures we go on to traverse nested symlinks by calling realpath
recursively on the symlink.
2. Makes glusterfs_realpath, a VMP-based operation, return a resolved
/real path that actually has the VMP pre-fixed to the resolved path.
If this is not done, we'll be returning a path that is valid only
within the glusterfs context, i.e. the path will point to a real
file/dir only if a glusterfs handle identifies which glusterfs context
the file is in.

libglusterfsclient: Guard against un-inited VMP searches
On my system, an selinux module gets inited before
booster even though the FS calls from the selinux module
get routed through our LD_PRELOAD'ed wrappers. In this
scenario, the VMP list is un-inited, resulting in a seg-fault
if it is dereferenced. The list_empty check does not help
because the pointers in the list have non-NULL values.

io-threads: Clarify thread count range
This patch cleans up io-threads behaviour regarding the
range values that can be specified for min-threads
and max-threads. THe major change is that the min threads
have been reduced to 2 to signify that io-threads needs minimum
two threads for its operation, while keeping the default number of
threads at 16. The idea is to decouple the default thread count
from the minimum thread count.
Note to Avati:
This applies over Raghu's indentation and logging take-3 patch.

fd leak fix
steps:
- server_finodelk uses req->volume pointer into state->volume
- finodelk is queued by locks translator
- c call returns from server_pollin and hdr is FREE'd
- now state->volname is pointing to FREE'ed region (junk)
- server_finodelk_cbk calls gf_add_locker
- gf_add_locker remembers lock with junked path along with fd_ref
- gf_del_locker from new server_finodelk cannot string match with junked volume thus
lock is not deleted, hence fd_ref remains as a leak

posix: Ensure EINVAL return on NULL args
Initing op_errno to EINVAL ensures that this is the value
that gets returned on STACK_UNWIND, in case any of the VALIDATE macros
result in exit from "out" due to a NULL argument. If this is not done
, we get op_ret as -1 with errno set to 0 in the application's
syscall.

libglusterfsclient: Fix stat cache bug
The way stat cache gets updated was not consistent across
all syscalls. Consequently, I was running into a bug that
returned a 0 st_ino. The fix actually resides in the hunk
that changes the lines in libgf_client_lookup but similar
changes were also required in other users of stat cache.
This commit fixes the bug and also cleans up the way stat
cache is updated.

libglusterfsclient: Add virtual mount point support
One part of the glusterfsclient library requires users
to use a handle to address a particular glusterfs context.
This can become cumbersome for applications that need to use multiple
such context. For such applications, we make it easy by letting them
define virtual mount points(VMPs), which are just paths that identify
a particular glusterfs context. This is done through a new
glusterfs_mount(..) interface.
Subsequenly, any path based operations, that pre-pend a VMP before
the files and directories inside the glusterfsd export, get internally
routed to the correct glusterfs context. This helps users do away
with the need to maintain their own path-to-glusterfs_handle_t
mapping.
The old handle-based interface still exists for whoever wishes to use
it.

client_protocol_reconnect - do not send notify of CHILD_DOWN event if errno from transport_connect() was EINPROGRES
This bug was racing between a CHILD_UP from poll thread resulting from the event_register() of the new socket called in fuse thread. CHILD_UP would sometimes overtake the CHILD_DOWN for EINPROGRESS. So replicate would receive CHILD_DOWN as the latest event. This resulted in self-heal not happening etc.

libglusterfsclient: Abstract away inode attr cache updates
This commit creates a separate function that allows users of
the inode attribute cache to update the cache when required.
Major users are lookup, stat and fstat functions.
The function libgf_update_iattr_cache(..) allows updating the lookup
and stat caches separately using flags.

libglusterfsclient: Fix segfault on non-NULL loc->name
The gf_log message actually assumes that loc->name will have a valid
non-NULL name in it, whereas if the loc_t being passed to it was
actually created on a function stack, i.e. a local function variable
and was then passed down the code path to do_path_resolve without ever
initing it or zeroing the structure, its possible that the name member
has a non-NULL but corrupted address. This leads to a segfault.
Whereas, we know loc->path will always have the full path.

2. best effort to write data in chunks of length as close to aggregate-size
as possible but not greater than aggregate-size, since aggregate-size is

libglusterfsclient: Perform explicit create
We must create the file based on the O_CREATE in the flags

in case this was actually an open and not create.

libglusterfsclient: Handle O_CREAT on lookup failure
On lookup failure, if O_CREAT is required, then we must:
1. explicitly lookup the parent directory.
2. create a new inode for the new file being opened.
This special case is required for file creation because:
1. We cannot depend on the previous lookup to have reliably looked up
the parent inode.
2. inode for the new file does not exist in the itable.

libglusterfsclient: Resolve path on empty caches
The earlier case was that the explicit lookups to the server
were being sent only when the parent inode was NULL. This situation
breaks when the parent inode is available in the i- or d-cache
but the child dirent is not. In such a case, no explicit lookups
were being sent to get the missing child dirent.
Now, explicit path lookup happens even if the inode for parent or basename
is not found in the caches.
This also fixes a seg-fault occuring during glusterfs_open, in my test
case, but one that could occur almost anywhere lookup code is used.

libglusterfsclient: Fix segfault in glusterfs_open
libgf_client_loc_fill gets passed a name=NULL argument.
So when this function returns the filled loc argument, this loc
is actually missing the inode structure that was to be filled.
The segfault actually occurs a few lines later when
we try to access fd->flags but fd returned by fd_create is NULL
because we'd passed a NULL inode to it, i.e. the loc->inode.

io-threads: Refactor ordered worker exit path
This patch re-factors the exit path of an ordered worker
on a time-out. Earlier we're checking for exit permission
in such a way that required us to release and acquire
the worker lock a second time in the worker loop opening
a window wherein a new request could've been appended to the
request queue.
This patch makes the decision to exit while still holding on to the
worker lock.

Fix in return value of afr_sh_mark_sources
afr_sh_mark_sources now returns:
-1 if two wise subvols conflict (split-brain)
0 if all subvols are innocent (no self-heal needed)
>0 if sources found
Also, changes to callers of afr_sh_mark_sources to handle return
value properly.

io-threads: Support autoscaling volfile options
This commit finally makes the autoscaling feature visible to the user.
Know that we're now using two separate thread-pools, one for data
requests, called ordered thread-pool in io-threads, and the other
for meta-data requests, called un-ordered thread-pool.
We do not expose this information to the user to keep io-threads
simple. Consequently, when the user specifies a min-threads and
max-threads value, the number of threads assigned to each pool
is equal, i.e. both pools start with their min threads set to half of
the option "min-threads" and both scale up their threads at most up to
half of option "max-threads".
Volfile options will be added to the wiki and user-guide.

This commit adds everything needed to:
a. Get un-ordered request going through the un-ordered
thread-pool. This happens through, the
iot_schedule_unordered(..). The unordered thread-pool
consists of thread running the iot_worker_unordered(..)
function.
b. Make threads in the un-ordered thread pool start-up
and exit depending on the thread state.
Note that at this point the requests that need
ordering are still going through iot_schedule(..).

io-threads: Classify requests for threadpool type
New io-threads will serve requests through two separate
threadpools.
One thread pool for requests that must be ordered
on a file that is open. so that the server can process the requests
in the order they were entered in the requests queue, and not in the order
the io-thread is able to send a request, which in turn is determined
by how the thread gets scheduled. This can also be called the
data-intensive ops thread pool.
Second thread-pool for requests that dont care about ordering, i.e.
requests like lookup, open, create, mkdir, etc.

IO-threads Cleanup: Clean-up request scheduling and queueing interface.
This patch does two things:
1. Cleans up the request scheduling and queueing interface so that all
fops only need to call iot_schedule and not iot_queue and in some
cases iot_schedule.
2. Till now, we've had open and create calls go through the main
glusterfsd thread when sending open and create fops. This patch makes
them also go through the worker threads. But since the open and
creates requests would not be called with a valid inode number in the
loc_t, these requests will get assigned to the worker at index 0.
This will be fixed RSN, when we introduce various techniques of
distributing the inodes(..not requests..) over the worker threads.

IO-threads Cleanup: Change workers list to dynamically allocated array
Worker threads were represented as a list in iot_conf_t
which made us traverse the list of workers in order to
decide which thread gets the request. Now we represent the
workers as a dynamically allocated array so that we can just index
into the array to schedule the file.
