Ok, the different ownership is limited within shitfs (or userns,
container). Good. I might forget that shiftfs wants to behave like
bind-mount.
And I noticed that shiftfs setattr() converts uid/gid before calling
backend fs' ->setattr(). It is good too.
But how about acl? Won't such conversion be necessary for acl too?
