The best answer I can come up with is to allow rmdir/unlink to automatically umount trees from their respective dentries. Obviously this can't be done for regular (privileged) mounts, which must keep returning EBUSY in such situations. But for unprivileged mounts I can't see any fundamental issue with such an approach. Does anyone see a problem with this? Is there a better solution?
