This commit should disappear from linux-next soon. We did not expect
that it would cause these warnings. We first want to fix the callers
before we put it back.

But the fix is great and makes sense on its own.

The use of kthread_create_worker() simplifies the code. It uses
the kthread worker API the right way. It will eventually allow
to remove the FIXME in kthread_worker_fn() and add more consistency
checks.

I would use the above reasoning instead of the backtrace in the commit
message. And feel free to use:
