[GIT PULL] cgroup fixes for v3.15-rc5

[Tejun Heo <tj@kernel.org>]

Hello, Linus.

During recent restructuring, device_cgroup unified config input check
and enforcement logic; unfortunately, it turned out to share too much.
Aristeu's patches fix the breakage and marked for -stable backport.

The other two patches are fallouts from kernfs conversion.  The blkcg
change is temporary and will go away once kernfs internal locking gets
simplified (patches pending).

The following changes since commit c9eaa447e77efe77b7fa4c953bd62de8297fd6c5:
