From 90aaca852ca13a6c962b25964fb6678120f266b1 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Thu, 25 Feb 2021 17:17:59 -0800 Subject: mm/rmap: fix obsolete comment in __page_check_anon_rmap() Commit 21333b2b66b8 ("ksm: no debug in page_dup_rmap()") has reverted page_dup_rmap() to an inline atomic_inc of mapcount. So page_dup_rmap() does not call __page_check_anon_rmap() anymore.
