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".
