Dave and Daniel, this question is still pertinent.

I understand the feeling. Recently I merged a patch from Vinay relying
on patchwork to get the reviewed-by and I forgot to double check.

dim picks up the "Link:", but I don't believe it picks any ack or rv-b
from the mailing list. Patchwork does if you use pwclient or something
like that.

Anyway, lesson to both of us to always double-check, regardless the
tool used.

That's my fault indeed. I was following the movement, but I failed
to step up right after I saw Greg's ack.
Although I also noticed some re-send and reviews in progress even
after the ack, I should had been more active there.

Sorry,
Rodrigo.
