Ignoring namespace details for a moment. The following should be
possible with a unified hierarchy.  If it is not it is a show stopper
of a regression.

The -o SUBSYS option doesn't exist.  Jesus, at least get yourself
familiar with the basics before claiming random stuff.

Not random and I am familiar thank you very much.

I may have mistyped the manual command line configuration for specifying
which controllers appear on a mount point does not alter my point.

The old options to enable selecting controllers need to continue and
need to continue to work with a unified hierarchy.

Anything else is a gratuitious regression.

Hmmm?  You were talking about the old hierarchies?

I have no idea what you're on about.  If the outer system uses unified
hierarchy, the inner system should use that too.  If the outer system
doesn't use unified hierarchy, namespace support has never existed,
and even if it did, the inside could never pick and choose controllers
independent from the outside.  If the outside is co-mounting cpu and
cpuacct, the inside is either also doing that or not mounting either.
