The Coverity checker spotted the following inconsequent NULL checking in
fs/ocfs2/dlmglue.c:
<-- snip -->
...
int ocfs2_meta_lock_atime(struct inode *inode,
struct vfsmount *vfsmnt,
int *level)
{
...
if (ocfs2_should_update_atime(inode, vfsmnt))
ocfs2_update_inode_atime(inode, bh);
if (bh)
brelse(bh);
...
<-- snip -->
Since commit c11e9fafb398411af7558fca913c2fa4a10b1f48
ocfs2_update_inode_atime() contains an unconditional
dereference of "bh".

of the darkness. There had been need of rain for many days.
"Only a promise," Lao Er said.
