Subject: [PATCH v1 13/18] mm/filemap: use folio_mapcount() in filemap_unaccount_folio()
Date: Tue,  9 Apr 2024 21:22:56 +0200

We want to limit the use of page_mapcount() to the places where it is
absolutely necessary.

Let's use folio_mapcount() instead of filemap_unaccount_folio().

No functional change intended, because we're only dealing with small
folios.
