Yes.  Christoph insisted that the bio conversion patch be split up.  That
means there's an interval where you can get FOLL_GET from that.

The only place where we have both is in the block layer.  It never gets
set by bio_set_cleanup_mode.

Instead we can just keep using put_page dirctly for the BIO_PAGE_REFFED
case in the callers of bio_release_page and in bio_release_pages itself,
and then do away with bio_to_gup_flags and bio_release_page entirely.

Thank you, just what I had in mind ...
