I was wondering why I didn't see this mail in patchwork:

https://patchwork.kernel.org/patch/11257187/

And then I noticed this:

X-Patchwork-Hint: ignore

kbuild team, why are you adding that header? It's really bad for a
thanks for the feedback, early on we received another feedback to suggest
for adding this, refer to https://gitlab.freedesktop.org/patchwork-fdo/patchwork-fdo/issues/21
for detail. Since there's no further input regarding this usage, we keep
that flag. If this is not suitable, we can investigate other way to fullfill
both requirements.

I second Kalle's comment; this is really bad.

Note that the above referenced link suggested to add
	X-Patchwork-Hint: comment
to e-mail headers. Instead, you added:
	X-Patchwork-Hint: ignore
which is substantially different. Also, the problem was with a _patch_
sent by the robot, not with direct feedback. On top of that, the
suggestion was really to add "X-Patchwork-Hint: comment" to _patches_
sent by the robot, not to everything. It should be fine to add
"X-Patchwork-Hint: ignore" to patches only as long as other feedback
is still provided and added to patchwork. That should meet all
requirements.

Thanks,
Guenter

Hi Kalle, Guenter

Thanks so much for your help, we have removed the hint header in build report mails and
still keep it in patch mails.

Best Regards,
Rong Chen


maintainer like me who uses patchwork actively, it means that all these
important warnings are not visible in patchwork and can be easily missed
by the maintainers.
