Re: Tejun's modifications for CPU hotplug and workqueues

Hello!

Tejun just this week posted patches that park the workqueue kthreads, which should reduce CPU-online latency under load. The easiest way to get these patches appears to be to pull them from Tejun's git tree:

git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git review-wq-hotplug

They pass some extremely mild rcutorture/hotplug testing, and more testing will follow. Please take a look at these and give them a go.

Thanx, Paul
