It can't. Per your latest branch:
Yes it can. Patch 6:
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.
In case this series gets resend (which I assume), it would be great to
CC linux-mm on the whole thing.
