Subject: [PATCH 0/4] workqueue: Destroy workers in idle_cull_fn().

From: Lai Jiangshan <jiangshan.ljs@...group.com>

After e02b93124855("workqueue: Unbind kworkers before sending them to
exit()"), the code to kick off the destruction of workers is now in a
process context (idle_cull_fn()), more destruction code can also be
moved to the said process context to simplify the destroying.

Cc: Valentin Schneider <vschneid@...hat.com>

Lai Jiangshan (4):
  workqueue: Reap workers via kthread_stop() and remove
    detach_completion
  workqueue: Don't bind the rescuer in the last working cpu
  workqueue: Detach workers directly in idle_cull_fn()
  workqueue: Remove useless pool->dying_workers
