[GIT PULL] cgroup changes for v4.15-rc1

[Tejun Heo]

Hello, Linus.

cgroup changes for v4.15-rc1.  cgroup2 cpu controller support is
finally merged.

* Basic cpu statistics support to allow monitoring by default without
  the CPU controller enabled.

* cgroup2 cpu controller support.

* /sys/kernel/cgroup files to help dealing with new / optional
  features.

The merge causes conflicts in two files - kernel/cgroup/Makefile and
kernel/cgorup/cpuacct.h.  Both are trivial conflicts from the license
identifier addition.  Makefile resolution is trivial and cpuacct.h no
longer exists.

Please expect another merge conflict with the bpf changes.  It's
caused by two additions to the cgroup_create() error handling path.
The resolution in the linux-next is correct.

Thanks.
