[PATCH v1 13/18] mm/filemap: use folio_mapcount() in filemap_unaccount_folio()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
