Subject[PATCH RESEND 0/1] sched/rt: minimize rq->lock contention in, do_sched_rt_period_timer()
Date
Peter, Ingo,

I sent this patch about a month ago and got no response.

https://patchwork.kernel.org/patch/9684545/

Does it seem reasonable? I'm not sure if taking rt_runtime_lock is
strictly necessary, but it's a big improvement to taking rq->lock every
pass through the loop. Is there another way to fix this?

Thanks,
Shaggy
