This is backport of the series for the following stable trees:
+ 4.9
+ 4.14
+ 4.19
The orignal series did not apply because of a conflict with the commit
("kthread: Convert worker lock to raw spinlock").
Petr Mladek (2):
kthread_worker: split code for canceling the delayed work timer
kthread: prevent deadlock when kthread_mod_delayed_work() races with
kthread_cancel_delayed_work_sync()
