This is the attribute belong to cpuset cgroup isn't it?

Forgive me but I have no idea on how to combined this
with memory cgroup's locality hierarchical update...
parent memory cgroup do not have influence on mems_allowed
to it's children, correct?

What about we just account the locality status of child
memory group into it's ancestors?
