For ->set_acl that's fairly easily doable and I actually had a version
doing that to be able to convert 9p.  But for ->get_acl the path walking
caller didn't seem easily feasible.  ->get_acl actually is an invention
of yours, so if you got a good idea to get the dentry to it I'd love
to be able to pass it.
