Hi Johannes,

Do you think it makes sense to have the below for both the baseline and
MGLRU or it's some behavior change that the baseline doesn't want to
risk?

It looks good to me. Besides the new FMODE_NOREUSE, it's also a nice
cleanup on the rmap side!

It would just be good to keep the comment from folio_referenced_one() and
move it to the vma_has_locality() check in invalid_folio_referenced_vma().

Otherwise,
