My test with sysfs node's meminfo seems to work...

[root@rx100-1 qqm]# mount --bind /sys/devices/system/node/node0/meminfo

[root@rx100-1 qqm]# cat /proc/meminfo

Node 0 MemTotal: 8379636 kB

This doesn't seem like a good idea unless the application supports the
"Node 0" prefix in /proc/meminfo.

Of course, /cgroup/memory/..../memory.meminfo , a new file, will use the same
format of /proc/meminfo. Above is just an example of bind-mount.


It's not just a memcg issue, it would also be a cpusets issue.

I think you can add cpuset.meminfo.

Thanks,
