Sorry, would you make one minor change? The "frequency" extension is
read-only so there is no need for a _write parameter (it'll always be
NULL).

You don't need to rebase and submit the entire patchset again just yet
because I will likely have more comments when I review. Just submit the
next version of this particular patch separately and I'll pick it up so
we can get it merged into counter-next.

Thanks,

William Breathitt Gray
