Yes, or else have built-in stubs for the cgroup subsystem that load
cfq and the code that uses cfq the first time someone tries to mount
that subsystem.

Actually, it probably wouldn't be too hard to have cgroups do that
automatically - support the concept of a stub cgroup that was known
about at compile time but wasn't active until its first bind, and have
cgroups dynamically load the relevant modules when the user tried to
mount it.

Dynamically loading subsystems that aren't even known about at compile
time would be probably a bit uglier.
