From da162e9368990ed747075e2ab427da0759fc4a59 Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Wed, 22 Feb 2017 15:46:31 -0800 Subject: mm: drop zap_details::ignore_dirty The only user of ignore_dirty is oom-reaper. But it doesn't really use it. ignore_dirty only has effect on file pages mapped with dirty pte. But oom-repear skips shared VMAs, so there's no way we can dirty file pte in them.
