Recently, Lee Schermerhorn developed numa-introduce-numa_mem_id-effective-local-memory-node-id-fix2.patch Then, you can use cpu_to_mem() instead of cpu_to_node() to find the nearest available node. I don't check cpu_to_mem() is synchronized with NUMA hotplug but using cpu_to_mem() rather than adding = + if ((nid == -1) || + !(node_zonelist(nid, GFP_KERNEL)->_zonerefs->zone)) + nid = numa_node_id(); + == is better.
