   This function loops over the pipe and calls <em class="parameter"><code>actor</code></em> to do the
   actual moving of a single struct pipe_buffer to the desired
   destination.  It returns when there's no more buffers left in
   the pipe or if the requested number of bytes (<em class="parameter"><code>sd</code></em>-&gt;total_len)
   have been copied.  It returns a positive number (one) if the
   pipe needs to be filled with more data, zero if the required
   number of bytes have been copied and -errno on error.
   </p><p>

   This, together with splice_from_pipe_{begin,end,next}, may be
   used to implement the functionality of <code class="function">__splice_from_pipe</code> when
   locking is required around copying the pipe buffers to the
   destination.
