cgroup v2 介紹

# Linux 4.5

cgroups v2 及 v1 可以同時存在

v2 = unified cgroup hierarchy

 * The unified CGroup hierarchy does not have CGroup V1 device controllers.

Check Kernel support V2

grep cgroup /proc/filesystems

nodev   cgroup
nodev   cgroup2

Controllers are available for cgroups-v2

 * A resource controller can be used either in a cgroups-v1 hierarchy or a cgroups-v2 hierarchy,

    not simultaneously in both.
