[GIT PULL] cgroup fixes for v3.16-rc4

[Tejun Heo]

Hello, again.

Mostly fixes for the fallouts from the recent cgroup core changes.
The decoupled nature of cgroup dynamic hierarchy management
(hierarchies are created dynamically on mount but may or may not be
reused once unmounted depending on remaining usages) led to more
ugliness being added to kernfs.  Hopefully, this is the last of it.

Thanks.
