[Andrew Morton]

The quilt patch titled
     Subject: rmap: pass the folio to __page_check_anon_rmap()
has been removed from the -mm tree.  Its filename was
     rmap-pass-the-folio-to-__page_check_anon_rmap.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: rmap: pass the folio to __page_check_anon_rmap()
Date: Thu, 6 Jul 2023 20:52:51 +0100

The lone caller already has the folio, so pass it in instead of deriving
it from the page again.
