This never involves the cleanup mode as input. And as I pointed out in the other mail, there is no need for the FOLL_ flags on the cleanup side. You can just check the bio flag in bio_release_apges and call either put_page or unpin_user_page on that. The direct callers of bio_release_page never mix them pin and get cases anyway. Let me find some time to code this up if it's easier to understand that way.
