From 2afd1c928f1132b8d0099866e75ce8ad713a1180 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 6 Jan 2009 14:39:26 -0800 Subject: [PATCH] mm: make page_lock_anon_vma() static page_lock_anon_vma() and page_unlock_anon_vma() were made available to show_page_path() in vmscan.c; but now that has been removed, make them static in rmap.c again, they're better kept private if possible.
