    [PATCH 2/2] ocfs2: Fix race between mount and recovery

ocfs2_mark_dead_nodes() was reading journal inodes while holding the
spinlock protecting our in-memory recovery state. The fix is very simple -
the disk state is protected by a cluster lock that's already held, so we
just move the spinlock down past the read.
