Improve performance by using a hash table or a faster approach for looking up ids. Currently an automatic "move-to-front-when-accessed" mechanism is implemented. Output more information in /proc/fusion. Improve performance (especially message throughput) by avoiding kmalloc. Implement defering/blocking of SIGSTOP while a Skirmish is locked by the process. This will avoid rare deadlocks when pressing Ctrl-Z in the terminal where a DirectFB slave application has been started. Revert semaphores to spinlocks where possible. Implement user space based skirmish_prevail()/dismiss() for the uncontended case, similar to futexes.
