v2->v3:
 - Change the generic CGRP_ROOT_V2_MODE flag to a cpuset specific
   CGRP_ROOT_CPUSET_V2_MODE flag.

v1->v2:
 - Drop the kernel command line option and use cgroupfs mount option
   instead to enable v2 controller behavior in v1 cgroup.

v1: https://lkml.org/lkml/2017/8/15/570

This patchset adds a new cgroupfs mount option "cpuset_v2_mode"
that enables the cpuset controller to use v2 behavior in a v1 cgroup.

Patch 1 adds the v1 cgroupfs mount option "cpuset_v2_mode" which set
a flag in the cgroup_root flags.

Patch 2 modifies the cpuset controller to check the cgroup_root flag
and switch to v2 behavior even in a v1 cgroup.

Waiman Long (2):
  cgroup: Add mount flag to enable cpuset to use v2 behavior in v1
    cgroup
  cpuset: Allow v2 behavior in v1 cgroup
