Subject: [PATCH 0/7] workqueue: Share the same PWQ for the CPUs of a pod and distribute max_active across pods

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

A different approach to fix the misbehavior can easily be exposed as reported in
http://lkml.kernel.org/r/dbu6wiwu3sdhmhikb2w6lns7b27gbobfavhjj57kwi2quafgwl@htjcc5oikcr3.

Lai Jiangshan (6):
  workqueue: Reuse the default PWQ as much as possible
  workqueue: Share the same PWQ for the CPUs of a pod
  workqueue: Add pwq_calculate_max_active()
  workqueue: Wrap common code into wq_adjust_pwqs_max_active()
  workqueue: Addjust pwq's max_active when CPU online/offine
  workqueue: Rename wq->saved_max_active to wq->max_active

Tejun Heo (1):
  workqueue: Implement system-wide max_active enforcement for unbound
    workqueues
