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

Lai Jiangshan (10):
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
