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.
Thanks.
