From 4d510f3da4c216d4c2695395f67aec38e2aa6cc7 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 11 Jan 2023 14:28:54 +0000 Subject: mm: add folio_add_new_anon_rmap() In contrast to other rmap functions, page_add_new_anon_rmap() is always called with a freshly allocated page. That means it can't be called with a tail page. Turn page_add_new_anon_rmap() into folio_add_new_anon_rmap() and add a page_add_new_anon_rmap() wrapper. Callers can be converted individually.
