Subject: 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.
