[PATCH 00/10] workqueue: restructure flush_workqueue() and start all flusher at the same time

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

The core patch is patch6, it makes all flusher can start and the same time
and allow us do more cleanup.

Only patch1 and patch6 change the behavior of the code.
All other patches do not change any behavior.

  workqueue: always pass flush responsibility to next
  workqueue: remove unneeded check
  workqueue: remove while(true)
  workqueue: use nr_cwqs_to_flush array
  workqueue: add wq_dec_flusher_ref()
  workqueue: start all flusher at the same time
  workqueue: simplify flush_workqueue_prep_cwqs()
  workqueue: assign overflowed flushers's flush color when queued
  workqueue: remove flusher_overflow
  workqueue: remove wq->flush_color
