Hello, Sorry for disturbing. I want to test how to use cgroup v2 on kernel 4.6.2. And I have read https://www.kernel.org/doc/Documentation/cgroup-v2.txt According to the above document, I added kernel parameter cgroup_no_v1=1. But, system still automount the v1 cgroup. Then, I executed: # mount -t cgroup2 none /mnt But, cgroup.controllers in /mnt is empty. I'm not sure if I made something wrong or cgroup v2 is not supported on kernel 4.6.2?
