Can you please go into details on what the expected use cases are like
for cgroupfs?  It shows up as a filesystem but isn't a real one and
has its own permission scheme for delegation and stuff.  If sysfs
hasn't needed selinux support, I'm having a bit of difficulty seeing
why cgroupfs would.

Thanks.
