Hello, Eric.

Does this allow mixing of cgroupfs and cgroupfs2?  That is can I: "mount

semantics of cgroups prevent this but I am interested to know what happens.
cgroup v1 and v2 are just separate hierarchies.  They can't nest each
other but co-existing and namespacing on their own is completely fine.
The caveat is that a given controller can be on only one hierarchy but
that's the same among v1 hierarchies too.

Thanks.
