Merge tag 'interrupting_kthread_stop-for-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull kthread update from Eric Biederman:
"Break out of wait loops on kthread_stop()
This is a small tweak to kthread_stop so it breaks out of
interruptible waits, that don't explicitly test for kthread_stop.
These interruptible waits occassionaly occur in kernel threads do to
code sharing"
