From c5a73c3d55be1faadba35b41a862e036a3b12ddb Mon Sep 17 00:00:00 2001 From: Andrea Arcangeli Date: Thu, 13 Jan 2011 15:47:11 -0800 Subject: [PATCH] thp: use compaction for all allocation orders It makes no sense not to enable compaction for small order pages as we don't want to end up with bad order 2 allocations and good and graceful order 9 allocations.
