So I've always objected to these knobs.

That said; they are a pre-existing user interface so changing them isn't
really feasible much.

But at the very least we should integrate them properly. Which for
schedutil would mean they have to directly modify the relevant CPU
capacity values. Is this currently done? (I think not.)
