Subject: [PATCH -mm] enable CONFIG_COMPACTION by default
Date: Thu, 13 Sep 2012 16:21:04 -0400 [thread overview]
Message-ID: <20120913162104.1458bea2@cuia.bos.redhat.com> (raw)
Now that lumpy reclaim has been removed, compaction is the
only way left to free up contiguous memory areas. It is time
to just enable CONFIG_COMPACTION by default.
