From 05106e6a54aed321191b4bb5c9ee09538cbad3b1 Mon Sep 17 00:00:00 2001 From: Rik van Riel <riel@redhat.com> Date: Mon, 8 Oct 2012 16:33:03 -0700 Subject: mm: enable CONFIG_COMPACTION by default Now that lumpy reclaim has been removed, compaction is the only way left to free up contiguous memory areas.
