[Cluster-devel] [PATCH 17/22] GFS2: Fix spectator umount issue



The tests further down the recovery function relating to
unlocking the journal need to be updated to match the
intial test. Also, a test in the umount code which was
surplus to requirements has been removed. Umounting
spectator mounts now works correctly, as expected.
