From c034c6a45c977fdf33de5974d7def75bda9dcadc Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Tue, 10 Jan 2023 00:51:24 +0000 Subject: mm/sl{a,u}b: fix wrong usages of folio_page() for getting head pages The standard idiom for getting head page of a given folio is '&folio->page', but some are wrongly using 'folio_page(folio, 0)' for the purpose. Fix those to use the idiom.
