Hi, thanks for the response! And yes-I think this would actually be perfect
for what we need, I guess one question I might as well ask since I've got you
here: would patches to expose an unlocked version of kthread_queue_worker() be
accepted? With something like that I should be able to just reuse the
delayed_work_list and spinlocks that come with kthread_worker which would make
the vblank works implementation a bit easier
