-Subject: [PATCH] kernel: Enable memory compaction
-
-Compaction is the only memory management component to form high order (larger
-physically contiguous) memory blocks reliably. The page allocator relies on
-compaction heavily and the lack of the feature can lead to unexpected OOM
-killer invocations for high order memory requests. You shouldn't disable this
-option unless there really is a strong reason for it.
