It is the improved solution from thread http://lkml.org/lkml/2010/11/18/3, our draft patch set all the nodes as possbile node, it wastes a lot of memory, the command line numa=possible=<N> seems to be an acceptable, and it is a optimization for our patch. I like your active work attitude for the patch reviewing, it is real helpful to improve the patch quality. the NUMA Hotplug Emulator is an overall solution for Node/CPU/Memory hotplug emulation, it includes a lot of engineers' review comments and feedbacks in the mailling list. We review and test each version very carefully, and make sure each version is very stable and it includes in most of the feedbacks, so we deliver each version very slow. we do NOT want to split the emulator into many parts, and want to maintain them together. How about add this patch into our emulator patchset, and add your sign-off?.
