    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.

    Thanks.
