I was going to reply to this, too, but for another reason.
The last 'Acked-by: Adam Kaufman <adam.kaufman at pinnacle.com>'
was not posted publically by Adam anywhere as far as I can
see, so it should not appear in the commit message.
As for the meaning of Acked-by, I'm not so sure. We currently use
Signed-off-by as a tagging of "I wrote (parts of) this code"
(i.e. is has legal importance), and the Acked-by merely as
"ok, looks fine" indicator (but you didn't write the code).
Not sure how exactly the Linux kernel folks use these...
Sample scenario: Developer A posts a patch with a Signed-off-by,
you (developer B) modify/improve it and add your own Signed-off-by.
Then someone else (developer C) improves the patch even further, and
adds his Signed-off-by. Now you (B) post an Acked-by for this last
revision of the patch, i.e.
This makes sense to me. What would probably _not_ make any sense is
because you ack your own patch here, which defeats our purpose of the
Acked-by tag (enforce review by at least one developer).
Also, I don't think that a Signed-off-by necessarily means that you
ack the patch. It's possible that you just posted an improved version
of the patch (and added your Signed-off-by), but you still think that
it's not good enough to be committed, i.e. you don't want to ack it
at the moment...
