→CGroup-v2 support
=== CGroup-v2 support ===
=== CGroup-v2 support ===
'''Summary:''' cgroup is a mechanism to organize processes hierarchically and distribute system resources along the hierarchy in a controlled and configurable manner. cgroup v2 is a new version of the cgroup file system. Unlike v1, cgroup v2 has only single hierarchy. CRIU has to dump/restore a container cgroup hierarchy along with all per-cgroup options. The cgroupv2 support in CRIU has to be compatible with Docker, containerd and cri-o.
