Subject: [PATCH RESEND 0/1] sched/rt: minimize rq->lock contention in, do_sched_rt_period_timer()
Date: Mon, 15 May 2017 14:13:09 -0500	[thread overview]
Message-ID: <741689b4-2e37-bdfe-5953-bb954fe5c35a@oracle.com> (raw)

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
