So, the above should work too but I wonder whether we could do this
simpler.  Frankly, I wouldn't mind if cfq and bfq can't be mixed on a
system - e.g. they can be built together but you can't enable bfq on
some devides and cfq on others.  If we do that, all we need to do is
just removing / adding cftypes when either gets activated which cgroup
already does.

Thanks.
