Message-Id: <1436784852-144369-6-git-send-email-kirill.shutemov@linux.intel.com> Date: Mon, 13 Jul 2015 13:54:12 +0300 From: "Kirill A. Shutemov" <kirill.shutemov@...ux.intel.com> To: Andrew Morton <akpm@...ux-foundation.org>, Oleg Nesterov <oleg@...hat.com> Cc: linux-mm@...ck.org, linux-kernel@...r.kernel.org, "Kirill A. Shutemov" <kirill.shutemov@...ux.intel.com>, Johannes Weiner <hannes@...xchg.org>, Michal Hocko <mhocko@...e.cz> Subject: [PATCH 5/5] mm, memcontrol: use vma_is_anonymous() to check for anon VMA !vma->vm_file is not reliable to detect anon VMA, because not all drivers bother set it. Let's use vma_is_anonymous() instead. Signed-off-by: Kirill A.
