The patch titled Subject: mm/memcontrol.c: allocate shrinker_map on appropriate NUMA node has been removed from the -mm tree. Its filename was mm-allocate-shrinker_map-on-appropriate-numa-node.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Kirill Tkhai <ktkhai@xxxxxxxxxxxxx> Subject: mm/memcontrol.c: allocate shrinker_map on appropriate NUMA node The shrinker_map may be touched from any cpu (e.g., a bit there may be set by a task running everywhere) but kswapd is always bound to specific node. So allocate shrinker_map from the related NUMA node to respect its NUMA locality. Also, this follows generic way we use for allocation of memcg's per-node data.
