[PATCH v2 0/2] workqueue: Make the workqueue code PREEMPT_RT safe

From: Sebastian Andrzej Siewior
Date: Wed May 27 2020 - 15:47:10 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.

v1âv2: Use rcuwait instead of swait.
