Yeah - the counters aren't driven unless CONFIG_MOUNT_NOTIFICATIONS=y.

I could perhaps make it so they're driven in both cases, but driving the
in-subtree counter is somewhat tied up in the notification posting.

This is something that can be fixed after this patchset is taken - if it is
taken since that doesn't change the UAPI.
