I really wonder if 76a495d666e5 (ceph: ensure d_name stability in ceph_dentry_hash()) makes any sense; OK, you have ->d_lock held over that, but what does it protect against? Sure, you'll get something that was valid while you held ->d_lock, but what good does it do to the callers? If they really have to care about races with d_move(), which value do they want?
