GFS2: write_end error path fails to unlock transaction lock
I did an audit of gfs2's transaction glock for bugzilla bug 658619 and ran across this: In function gfs2_write_end, in the unlikely event that gfs2_meta_inode_buffer returns an error, the code may forget to unlock the transaction lock because the "failed" label appears after the call to function gfs2_trans_end.
