My eye can't check details enough but...;) Reviewed-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx> I think this patch itself is very good. Being more greedy... Hmm, from user's view, I feel quick guide of /sys/devices/system/node/ and /sys/devices/system/node/node0/numastat can be added somewhere. (Documentation/numastat.txt is not under /vm :( ) And one more important? thing. [kamezawa@firextal Documentation]$ cat /sys/bus/pci/devices/0000\:00\:01.0/numa_node -1 PCI device (and other??) has numa_node_id in it, if it has locality information. I hear some guy had to be aware locality of NIC to do high-throuput network transaction. Then, "how to get device's locality via sysfs" is worth to be written. And mentioning what "nid = -1" means may help new comer.
