[V2 for-next PATCH 0/7] workqueue: async idle rebinding and cleanup for hotplug

[Lai Jiangshan <laijs@cn.fujitsu.com>]

Patch1 fix new found possible bug.

Patch2 use async algorithm to replace the synchronous algorithm to rebind
idle workers.

The synchronous algorithm requires 3 hand shakes, it introduces much
complicated. 

The new async algorithm does not do any synchronization. it removes
the idle workers from idle_list to ensure the local-wake-up is correct
instead.

Patch3-7 do simple cleanup

Patch2-7 are ready for for-next. I have other devlopment and cleanup for workqueue,
should I wait this patchset merged or send them at the same time?

Lai Jiangshan (7):
  workqueue: clear WORKER_REBIND unconditionaly in
    busy_worker_rebind_fn()
  workqueue: async idle rebinding
  workqueue: new day don't need WORKER_REBIND for busy rebinding
  workqueue: remove WORKER_REBIND
  workqueue: rename manager_mutex to assoc_mutex
  workqueue: use __cpuinit instead of __devinit for cpu callback
  workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback()
