I applied this patch but there's a pending patchset to split legacy
and dfl cftype arrays, so maybe doing it separately makes more sense
now, I'm not sure. Anyways, we need to review cpuset interface for
the default hierarchy anyway. At least the memory pressure knobs
should go. It's measuring something which is completely
implementation dependent.
