I tested linux-next next-20130706 +part1+part2+part3 in a VM, hot-plugging memory and rebooting with movablecore=acpi. I think with this patch and 9/15 we get the correct nids and the expected behaviour for the "movablecore=acpi" option. However, patches 21,22 of part1 and all part3 patches increase kernel usage of local node memory by putting pagetables local to those nodes. Are these pagetable pages accounted in part2's memblock_kernel_nodemask? It looks like part1 and part3 of these patchsets contradict or make the goal of part2 more difficult to achieve. (I will send more comments for part3 separately). thanks, - Vasilis -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
