Dave, this patch is marked as Changes Requested on patchwork, but the v2
here looks good. There was no change request on it, only on the v1, and
they were satified on v2. The only info I asked on v2 was to know he had
a bigger plan for this, not sure if that's what caused confusion or not.

Thanks,
Marcelo
