Subject: [PATCH 0/7] workqueue: cleanup rebind_workers().
Date: Tue, 28 Aug 2012 01:58:20 +0800	[thread overview]
Message-ID: <1346090307-3020-1-git-send-email-laijs@cn.fujitsu.com> (raw)

These small patches change the rebind_workers() a little.

Patch1,5 fix possible bug.

Patch1,2 idle_worker_rebind() uses manage_mutex to wait rebind_workers()
	to finish and ease WORKER_REBIND

Patch3,4 makes rebind_workers() single pass and makes code clean.

Patch5 use single write instruction to void other CPU see wrong flags.

Patch6,7 small fix.

Lai Jiangshan (7):
  wait on manager_mutex instead of rebind_hold
  simple clear WORKER_REBIND
  explit way to wait for idles workers to finish
  single pass rebind
  ensure the wq_worker_sleeping() see the right flags
  init 0
  static idle_rebind
