Why not have schedtune be enabled always, and use it to add the margin? It seems like it'd simplify things.
I haven't looked at the schedtune code at all so I don't know whether this makes sense given its current implementation. But conceptually I don't know why we'd need or want one margin in schedutil which will be tunable, and then another mechanism for tuning as well.
