Subject: Re: [PATCH rfc 0/6] Scheduler BPF

Hi list,

Is there any reason why this patch only got a few comments so far?

IMHO, by using static keys, the patch should add barely observable overhead
to sched when no BPF progs loaded. Or is it because of the point that Yousef
mentioned earlier? I.e. sched BPF may encourage people to fix sched problems
with BPF progs instead of fixing sched directly.

Thanks!
