Date: Tue, 28 Feb 2017 16:40:02 -0500 From: Johannes Weiner <hannes@...xchg.org> To: Andrew Morton <akpm@...ux-foundation.org> Cc: Jia He <hejianet@...il.com>, Michal Hocko <mhocko@...e.cz>, Mel Gorman <mgorman@...e.de>, linux-mm@...ck.org, linux-kernel@...r.kernel.org, kernel-team@...com Subject: [PATCH 4/9] 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.
