The problem is exactly that it's filesystem specific, each filesystem
creates it's own stuff there.

Also we have a rule tp not create new things under /proc.  Things
should either go into /sys or into /proc/sys.  And I think a sysctl is
more appropriate for this than something under /sys.

Thanks,
Miklos
