Subject: Re: [PATCH 0/4] sched/fair: Burstable CFS bandwidth controller

The code for this looks fine, and the feature is something people do
seem to ask for occasionally. I agree with peterz that using this
generally means you lose any guarantees (which are already imperfect
given CFS), but I suspect that cfsb is being used in overload anyways.

The docs could use a grammar/wording pass maybe, but that's easy enough.
