I already have in plan to fix non-power-of-two sized memory nodes so I will this too. What exactly is the point in having NUMA memoryless nodes now? We do not support memory hotplug yet and balloon is not memory hotplug at all. And I still fail to see how the patch is wrong. May be the idea of having DT memory nodes the same thing as NUMA memory nodes is not the best one, but the patch is not changing that. -- Alexey
