Hi Linus,

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.du...@intel.com>, David S.
Miller" <da...@davemloft.net>
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?
TO: author
CC: committer (maintainer)
CC: all Signed-off-by
CC: all Reviewed-by
CC: mailing lists, if the bug is found in a maintainer/well known tree
Regards,
Fengguang
