From: Hannes Reinecke <hare@xxxxxxx> [ Upstream commit 489dc0f06a5837f87482c0ce61d830d24e17082e ] The only case where dmz_get_zone_for_reclaim() cannot return a zone is if the respective lists are empty. So we should just return a simple NULL value here as we really don't have an error code which would make sense.
