I think your missing something here. CKRM, as I understand it, aspires
to be a general purpose resource management framework. To that point I
will accede. But the second part, about CKRM being the embodiment of
fair share scheduling, is secondary. That is simply one of it's
potential functions as a general purpose resource management framework.
It could also be the embodiment of unfair scheduling, if you choose to
implement such a resource controller. It wouldn't be very useful, but
it could be a fun exercise! ;)

I don't think that is terribly fair. I can honestly say that I'm not
opposing your implementation because of who you work for. I could care
less. I'm opposing it because I think I've got an alternative that can
offer the same functionality with less impact. I don't work on CKRM,
and when I wrote my code CKRM was not even on my radar. If
sched_domains will play nicer with CKRM than cpusets, thats just a
bonus. I certainly didn't design it that way!

*More* analogies!?! ;)
