Description
As described in http://www.spinics.net/lists/ceph-devel/msg11872.html, we want hard links to contain lazily-updated backtraces. Add fields and logic so they have a backtrace on creation, and to update it whenever we do a lookup that requires reverting to lookup-by-ino from lookup-by-path.
