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
