Subject: [PATCH 00/10 V4] workqueue: fix and cleanup hotplug/rebind_workers()
Date: Sun, 2 Sep 2012 00:28:18 +0800 [thread overview]
Message-ID: <1346516916-1991-1-git-send-email-laijs@cn.fujitsu.com> (raw)
Patch 1~4 fix possible bugs.
Patch 1 fix possible double-write bug
Patch 2,5,6 makes the waiting logic more clear
Patch 3,4 fix bugs from manage VS hotplug
Patch 7,8,9,10 explicit logic to wait in busy-work-rebind and make rebind_workers()
single pass.
Change from V3.
A new approach to fix the bug manage VS hotplug. The new approach
still need POOL_MANAGING_WORKERS. so patch3 is kept.
busy-work-rebind wait on a different thing to wait all idles. so
the patch 8,9,10 's aim and changlog are almost not changed, but
the code are changed a little.(based on synchronize_all_idles_rebound())
Lai Jiangshan (10):
workqueue: ensure the wq_worker_sleeping() see the right flags
workqueue: fix deadlock in rebind_workers()
workqueue: add POOL_MANAGING_WORKERS
workqueue: add manage_workers_slowpath()
workqueue: move rebind_hold to idle_rebind
workqueue: simple clear WORKER_REBIND
workqueue: move idle_rebind pointer to gcwq
workqueue: explicit way to wait for idles workers to finish
workqueue: single pass rebind_workers
workqueue: merge the role of rebind_hold to idle_done
