This is a note to let you know that I have just added a patch titled Revert "mm/hugetlb: use pmd_page() in follow_huge_pmd()" to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt12. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 45edcd45af325f39d985f3d0ecee1c71376d8c34 Mon Sep 17 00:00:00 2001 From: Luis Henriques <luis.henriques@canonical.com> Date: Mon, 18 May 2015 11:01:04 +0100 Subject: Revert "mm/hugetlb: use pmd_page() in follow_huge_pmd()" This reverts commit 65342eab7baa43fb7852aafbe99e54daf2cd6420 which is commit 97534127012f0e396eddea4691f4c9b170aed74b upstream. This is being reverted because it fixes a regression that was introduced in 4.0 and does not affect 3.16 kernel.
