[systemd-devel] How does hybrid cgroup setup work?

[Umut Tezduyar Lindskog]

Hello,

I am trying to have cpu controller on v1 and memory controller on
unified but it is not working the way I am expecting. When I enable
CONFIG_MEMCG, cgroup is popping up in /proc/cgroups and
mount_cgroup_controllers() is mounting it very early. Once it is
mounted in v1, it becomes unavailable in v2.

Did I misunderstand how hybrid works?
