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

From: Tejun Heo
Date: Tue Sep 05 2017 - 10:39:48 EST

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
