From 4b5972b179c37b572762a6c0b24ca5d0a7080a64 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 14 Mar 2013 15:49:59 +0000 Subject: [PATCH] GFS2: Fix unlock of fcntl locks during withdrawn state When withdraw occurs, we need to continue to allow unlocks of fcntl locks to occur, however these will only be local, since the node has withdrawn from the cluster.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.
