Subject: mm/damon: convert damon_pa_mark_accessed_or_deactivate() to use folios
Date: Wed, 21 Dec 2022 10:08:47 -0800
This change replaces 2 calls to compound_head() from put_page() and 1 call
from mark_page_accessed() with one from page_folio(). This is in
preparation for the conversion of deactivate_page() to folio_deactivate().
