Subject: [GIT PULL] cgroup changes for v4.14-rc1

Hello, Linus.

Several notable changes this cycle.

* Thread mode was merged.  This will be used for cgroup2 support for
  CPU and possibly other controllers.  Unfortunately, CPU controller
  cgroup2 support didn't make this pull request but most contentions
  have been resolved and the support is likely to be merged before the
  next merge window.

* cgroup.stat now shows the number of descendant cgroups.

* cpuset now can enable the easier-to-configure v2 behavior on v1
  hierarchy.

Thanks.
