[Ocfs2-devel] [PATCH 1/2] cannot metex_unlock without mutex_lock in ocfs2_remove_btree_range

[Joseph Qi]

In ocfs2_remove_btree_range, when calling ocfs2_lock_refcount_tree and
ocfs2_prepare_refcount_change_for_del failed, it goes to out and then
tries to call mutex_unlock without mutex_lock before.
