From cd67f0d2a9a6b5b9f79f4343dc8805757d9ebae2 Mon Sep 17 00:00:00 2001 From: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Date: Fri, 10 Sep 2010 13:23:04 +0900 Subject: [PATCH] hugetlb, rmap: use hugepage_add_new_anon_rmap() in hugetlb_cow() Obviously, setting anon_vma for COWed hugepage should be done by hugepage_add_new_anon_rmap() to scan vmas faster. This patch fixes it.
