Yes like that. This was actually discussed during the initial cpuset
implementation. I thought back then it would be better to do it
elsewhere, but changed my mind later when I saw the impact on the
fast path.

Yes you would need one per node, but that's not a big problem because
systems with lots of nodes are also expected to have lots of memory.
Most systems have a very small number of nodes.
