Subject: ocfs2: goto out_unlock if ocfs2_get_clusters_nocache() failed in
ocfs2_fiemap()
From: Joseph Qi <[email protected]>
commit b4ca2b4b577c3530e34dcfaafccb2cc680ce95d1 upstream.
Last time we found there is lock/unlock bug in ocfs2_file_aio_write, and
then we did a thorough search for all lock resources in
ocfs2_inode_info, including rw, inode and open lockres and found this
bug. My kernel version is 3.0.13, and it is also in the lastest version
3.9. In ocfs2_fiemap, once ocfs2_get_clusters_nocache failed, it should
goto out_unlock instead of out, because we need release buffer head, up
read alloc sem and unlock inode.
