Describe the bug
Although FreezerController supports cgroups v2, it is not included in Cgroup, because cgroups v2 do not have "freezer" as a controller, but it's implemented directly via cgroup.freeze (and thus "freezer" is not included in cgroup.controllers).
Expected behaviorFreezerController is supported also with cgroups v2.
Additional context
Observed on linux 5.10 and 5.14 (NixOS 21.05).
