From: Johannes Weiner <hannes@xxxxxxxxxxx> Subject: mm: remove unnecessary reclaimability check from NUMA balancing target NUMA balancing already checks the watermarks of the target node to decide whether it's a suitable balancing target. Whether the node is reclaimable or not is irrelevant when we don't intend to reclaim.
