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. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Michal Hrusecky <michal.hrusecky@nic.cz>
