Hi Michal,
We used the default configure of cgroups, not sure what configuration you want, could you give me more details? and here is the cgroup info of will-it-scale process:
$ cat /proc/3042/cgroup 12:hugetlb:/ 11:memory:/system.slice/lkp-bootstrap.service 10:devices:/system.slice/lkp-bootstrap.service 9:cpuset:/ 8:perf_event:/ 7:rdma:/ 6:freezer:/ 5:pids:/system.slice/lkp-bootstrap.service 4:net_cls,net_prio:/ 3:blkio:/ 2:cpu,cpuacct:/ 1:name=systemd:/system.slice/lkp-bootstrap.service
Best Regards, Rong Chen
