The following series adds support for:
- named cgroup hierarchies
- cgroup hierarchies with no bound subsystems
- cgroup subsystems that can be bound to multiple hierarchies
This allows more flexibility when constructing/mounting cgroups
hierarchies, and allows functionality that's not tied to specific
external resources to be made available on multiple cgroups
hierarchies rather than just one.
A few simple example cgroups subsystems that are multi-bindable are
included in the patch series.
