  workqueue: Don't rely on wq->rescuer to stop rescuer (2025-11-21 09:45:36 -1000)

----------------------------------------------------------------
workqueue: Changes for v6.19

- Rescuer affinity management: Affinity now updated only when detached using
  wq_unbound_cpumask consistently. DISASSOCIATED workers also follow unbound
  cpumask changes to avoid breaking CPU isolation.

- Rescuer cleanups preparing for fetching work items one by one from pool list:
  Work assignment factored out, optimized to skip pwqs no longer needing
  rescue, and shutdown logic simplified.

- Unused assert_rcu_or_wq_mutex_or_pool_mutex() removed.

----------------------------------------------------------------
Lai Jiangshan (6):
      workqueue: Update the rescuer's affinity only when it is detached
      workqueue: Let DISASSOCIATED workers follow unbound wq cpumask changes
      workqueue: Init rescuer's affinities as wq_unbound_cpumask
      workqueue: Factor out assign_rescuer_work()
      workqueue: Only assign rescuer work when really needed
      workqueue: Don't rely on wq->rescuer to stop rescuer

zhang jiao (1):
      workqueue: Remove unused assert_rcu_or_wq_mutex_or_pool_mutex
