3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Steven Whitehouse <[email protected]> commit c2952d202f710d326ac36a8ea6bd216b20615ec8 upstream. When withdraw occurs, we need to continue to allow unlocks of fcntl locks to occur, however these will only be local, since the node has withdrawn from the cluster. This prevents triggering a VFS level bug trap due to locks remaining when a file is closed.
