[PATCH 0/3] workqueue: Make the workqueue code PREEMPT_RT safe
From: Sebastian Andrzej Siewior
Date: Wed May 13 2020 - 12:27:45 EST
The series changes `wq_manager_wait' from waitqueues to simple
waitqueues and its internal locking (pool::lock and wq_mayday_lock) to
raw spinlocks so that workqueues can be used on PREEMPT_RT from truly
atomic context.
