Hello, Greg.
The following two patches that just pulled by Linus need to be backported to -stable but don't have stable tagged on them.
v5.2+ : 07edfece8bcb ("workqueue: Fix unbind_workers() VS wq_worker_running() race") v5.16+: 45c753f5f24d ("workqueue: Fix unbind_workers() VS wq_worker_sleeping() race")
Can you please include them in -stable backports?
Thank you.
