From: Naoya Horiguchi Date: Fri, 10 Sep 2010 04:23:04 +0000 (+0900) Subject: hugetlb, rmap: use hugepage_add_new_anon_rmap() in hugetlb_cow() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cd67f0d2a9a6b5b9f79f4343dc8805757d9ebae2;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git 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.
