Eh, you're right. I want to remove support for duplicate mounting by name or subsys as it just isn't necessary, so what I want is,
* "mount -t cgroupfs -o SUBSYS" will fail if SUBSYS is already mounted somewhere else.
* "mount -t cgroupfs -o none" will always create a new cgroup hierarchy w/o any controller attached.
I didn't realize that the mount code didn't allow none w/o name and now I don't see a non-intrusive way to remove the name option. :( Eh well, I'll drop that part.
Thanks.
