Date: Fri, 10 Sep 2010 13:23:04 +0900 From: Naoya Horiguchi <n-horiguchi@...jp.nec.com> To: LKML <linux-kernel@...r.kernel.org> Cc: Andrea Arcangeli <aarcange@...hat.com>, Hugh Dickins <hughd@...gle.com>, Christoph Lameter <cl@...ux.com>, Linus Torvalds <torvalds@...ux-foundation.org>, Andrew Morton <akpm@...ux-foundation.org>, Rik van Riel <riel@...hat.com>, Peter Zijlstra <peterz@...radead.org>, Andi Kleen <andi@...stfloor.org>, linux-mm <linux-mm@...ck.org> Subject: [PATCH 2/4] 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.
