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 "v2_mode" that serves as a hint that a v1 controller can use v2 hehavior, if applicable. The cpuset controller is then modified to observe this mode.
Patch 1 adds the v1 cgroupfs mount option "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 a hint to allow v1 controller to use v2 behavior cpuset: Allow v2 behavior in v1 cgroup
