I also noticed that the kernel test robot had screwed up the
participants list for some reason, and had

"Acked-by: Alexander Duyck <alexander.h.duyck@xxxxxxxxx>, David S.
Miller" <davem@xxxxxxxxxxxxx>

as one of the participants. So there's some odd commit parsing issue
there somewhere. But Alexander seems to have seen this report despite
that, it just never went anywhere that I can tell.

Yeah the robot will CC all "Acked-by" people in the bug reports.

Shall we limit it to the below TO/CC list?

No. We do want to keep the Acked-by's on the cc.

But you missed the real problem.

It *didn't* cc the acked-by. Look closer. What happened was that it cc'd this:

"Acked-by: Alexander Duyck <alexander.h.duyck@xxxxxxxxx>, David S. Miller"


ie there is only _one_ email address (that of davem@xxxxxxxxxxxxx),
and the whole "Acked-by: Alexander Duyck <...>" part is quoted as the
_name_ of that email address.

At least that's what the headers look like for me in the original report:

From: kernel test robot <>
To: Eric Dumazet <edumazet@xxxxxxxxxx>
Cc: lkp@xxxxxx, Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>,
LKML <linux-kernel@xxxxxxxxxxxxxxx>, Alexei Starovoitov
<ast@xxxxxxxxxx>, Willem de Bruijn <willemb@xxxxxxxxxx>, "Acked-by:
Alexander Duyck <alexander.h.duyck@xxxxxxxxx>, David S. Miller"

Notice the quoting of that last "name".

Ah thanks! Xiaolong just root caused the parse error and will fix it.

Interestingly we didn't see that problem -- the CC list looks correct
in our emails -- perhaps Intel's email system auto fixed up the header.
