I don't mean to scope creep on you, but I have a couple of wishes related
to this topic:
- allow "rmdir" to remove an empty subvolume, i.e. when a subvolume is
detected in rmdir, try switching to subvol delete before returning
an error. This lets admin tools that are not btrfs-aware do 'rm
-fr' on a user directory when it contains a subvolume. Legacy admin
tools (or legacy tools in general) can't remove a subvol, and there
is no solution for environments where we can't just fire users who
create them.
- mount option to restrict "sub create" and "sub snapshot" to root only.
If we get "rmdir" working then this is significantly less important.
