Subject: [Ocfs2-devel] [PATCH] ocfs2: unlock rw lock if inode lock failed
Date: Mon, 6 May 2013 22:43:39 +0800 [thread overview]
Message-ID: <5187C19B.4040708@huawei.com> (raw)
In ocfs2_file_aio_write, it does ocfs2_rw_lock first and then
ocfs2_inode_lock. But if ocfs2_inode_lock failed, it goes to out_sems
without unlocking rw lock. This will cause a bug in ocfs2_lock_res_free
when testing res->l_ex_holders, which is increased in
__ocfs2_cluster_lock and decreased in __ocfs2_cluster_unlock.
