Oh let's see I got that command line option out of /proc/mounts and yes
it works.  Perhaps it doesn't if I invoke unified hiearchies but the
option does in fact exist and work.

Now I really do need to test report regressions, and send probably send
regression fixes.  If I understand your strange ranting I think you just
told me that option that -o SUBSYS does work with unified hierarchies.

Tejun.  I asked you specifically about this case 2 years ago at plumbers
and you personally told me this would continue to work.  I am going to
hold you to that.

Fixing bugs is one thing.  Gratuitious regressions that make supporting
existing user space applications insane is another.
