Jens, as I've mentioned in the previous mail, I handle the AUTOSEL mails weeks
after I originally sent them out for reviews.

The volume of mails and patches makes it really difficult to give prompt
answers here. I have no idea if 9cc6bac1bebf8310d2950d1411a91479e86d69a1
applies cleanly, whether I need to ask for a backport, or whether I should just
drop 45d2b37a37ab9848 until I sit down and get to this batch of AUTOSEL
commits.

If this process doesn't work well for you, I'm happy top skip all
non-stable-tagged commits for io_uring. This is supposed to be only a best
effort attempt to catch commits that slipped through the cracks.
