GFS2: Fix unlock of fcntl locks during withdrawn state (c2952d20) · Commits · 戴 / test

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we need to continue to allow unlocks of fcntl locks to occur, however these will only be local, since the node has withdrawn from the cluster.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. Signed-off-by:
