Yes indeed something similar to that. It's the scheduler changes I can't be
sure about, and of course we really need SEDF and credit2 changes as well,
hence I'd also like some feedback from George. Letting the scheduler peek
straight at per-cpu workqueues to check for work to do is a good idea
though. Easier than adding more scheduler hooks I think.

 Thanks,
 Keir
