Always zero in root cgroup?

Yes, if we're not accounting, it should be zero. WARN_ON, maybe?

-ENOSYS?

I'd personally prefer WARN_ON. It is good symmetry from userspace PoV to 
always be able to get a value out of it. Also, it something goes wrong 
and it is not zero for some reason, this will help us find it.

What's the point to get non-relevant value?
What about -ENOSYS + WARN_ON?
