Subject: [GIT PULL] cgroup changes for v3.17-rc1

Hello, Linus.

Mostly changes to get the v2 interface ready.  The core features are
mostly ready now and I think it's reasonable to expect to drop the
devel mask in one or two devel cycles at least for a subset of
controllers.

* cgroup added a controller dependency mechanism so that block cgroup
  can depend on memory cgroup.  This will be used to finally support
  IO provisioning on the writeback traffic, which is currently being
  implemented.

* The v2 interface now uses a separate table so that the interface
  files for the new interface are explicitly declared in one place.
  Each controller will explicitly review and add the files for the new
  interface.

* cpuset is getting ready for the hierarchical behavior which is in
  the similar style with other controllers so that an ancestor's
  configuration change doesn't change the descendants' configurations
  irreversibly and processes aren't silently migrated when a CPU or
  node goes down.

All the changes are to the new interface and no behavior changed for
the multiple hierarchies.

Thanks.
