Subject: mm/mempolicy: convert queue_pages_pmd() to queue_folios_pmd()
Date: Mon, 30 Jan 2023 12:18:29 -0800
The function now operates on a folio instead of the page associated with a
pmd.
This change is in preparation for the conversion of queue_pages_required()
to queue_folio_required() and migrate_page_add() to migrate_folio_add().
