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?
Well,
what about not even registering kernel memory files for !root cgroup?
