From ad8a20cf6d19a9506b4a554030bafc1ac204ef31 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Thu, 25 Feb 2021 17:18:06 -0800 Subject: mm/rmap: correct obsolete comment of page_get_anon_vma() Since commit 746b18d421da ("mm: use refcounts for page_lock_anon_vma()"), page_lock_anon_vma() is renamed to page_get_anon_vma() and converted to return a refcount increased anon_vma. But it forgot to change the relevant comment.
