Can we not add the effective interface file for now? I don't think
it's a bad idea but would like to think more about it. For cpuset, it
was needed because configuration was so interwoven with the effective
masks, but we don't generally do this for other min/max or weight
knobs, all of which have effective hierarchical values and I'm not
quite sure about adding .effective for all of them. It could be that
that's what we end up doing eventually but I'd like to think a bit
more about it.
