    Why? This should be "auto-tuning". We don't want to provide
    yet-another-knob-for-people-to-tweak-from-userspace, right?

    Ugh, that's just not a good thing at all. You can do that by running:
    echo /bin/true > /proc/sys/kernel/hotplug
    today if you have to. I don't like the ability to stop the kernel from
    running properly, like this patch allows you to.
