*Bangs self to desk*. You are right, didn't think that one through ;)

By the way, my v5 is ready to send. But I am avoiding sending it due to the
merge window going on. I posted it yesterday in this thread as well:
https://lore.kernel.org/patchwork/comment/1241077/

reviewers have any more comments.

thanks,
