Subject: [PATCH v5 0/2] cpuset: Enable cpuset controller in default hierarchy

v5:
 - Add patch 2 to provide the cpuset.flags control knob for the
   sched_load_balance flag which should be the only feature that is
   essential as a replacement of the "isolcpus" kernel boot parameter.

v4:
 - Further minimize the feature set by removing the flags control knob.

v3:
 - Further trim the additional features down to just memory_migrate.
 - Update Documentation/cgroup-v2.txt.

The purpose of this patchset is to provide a minimal set of cpuset
features for cgroup v2. That minimal set includes the cpus, mems and
their effective_* counterparts as well as a new flags control knob
that currently supports only the sched_load_balance flag.

This patchset does not exclude the possibility of adding more flags
and features in the future after careful consideration.

Patch 1 enables cpuset in cgroup v2 with cpus, mems and their
effective_* counterparts.

Patch 2 adds flags with support for the sched_load_balance only.

Waiman Long (2):
  cpuset: Enable cpuset controller in default hierarchy
  cpuset: Add cpuset.flags control knob to v2
