-    mksquashfs: fix rare race in fragment waiting in filesystem finalisation
-    
-    Fix a rare race condition in fragment waiting when finalising the
-    filesystem.  This is a race condition that was initially fixed in 2009,
-    but inadvertantly re-introduced in the latest release when the code
-    was rewritten.
-    
-    Background:
-    
-    When finalising the filesystem, the main control thread needs to ensure
-    all the in-flight fragments have been queued to the writer thread before
-    asking the writer thread to finish, and then writing the metadata.
-    
-    It does this by waiting on the fragments_outstanding counter.  Once this
-    counter reaches 0, it synchronises with the writer thread, waiting until
-    the writer thread reports no outstanding data to be written.
-    
-    However, the main thread can race with the fragment deflator thread(s)
-    because the fragment deflator thread(s) decrement the fragments_outstanding
-    counter and release the mutex before queueing the compressed fragment
-    to the writer thread, i.e. the offending code is:
-    
-                            fragments_outstanding --;
-                            pthread_mutex_unlock(&fragment_mutex);
-                            queue_put(to_writer, write_buffer);
-    
-    In extremely rare circumstances, the main thread may see the
-    fragments_outstanding counter is zero before the fragment
-    deflator sends the fragment buffer to the writer thread, and synchronise
-    with the writer thread, and finalise before the fragment has been written.
-    
-    The fix is to ensure the fragment is queued to the writer thread
-    before releasing the mutex.
