I see what you mean. If it is indeed the case than a mount of cgroupfs using the unified hiearchy and can not specify which controllers are present under that mount that very significant bug and presents a very significant regression in user space flexibility. I think you can still mount the unified hierarchy and select which controls you want to see. If you can not that is a change significantly past what was agreed to and a regression fix needs to be applied. With a unified hierarchy and separate controllers per mount many cgroup using applications will continue to work as before without changes, or with minimal changes. That is what was agreed to and what I expect has been actually implemented and it is what needs to be implemented in any case. I will see about making time to see where things are really at.
