this is another worthless bug report:

* No .config attached

* no build command line to know how you run sparse. I'm guessing with
C=1. But I should not have to guess.

Pls fix.

Thx.

Yeah, but that second report is not very helpful because nowhere it says
it is a summary and nowhere it has that link you pasted above so that
some other maintainer can go look.

Always put yourself in the recipient's shoes and ask yourself: "what can
the recipient do with this report and does it have everything in there
required to be able to reproduce the issue?"

If not, then it needs changing.

Yes, that would be much appreciated. You can also tag your reports with
a unique hash which is then in an URL so that one can go and download the
.config and what else is needed. For example...

Thx.

thanks for the advice. We will provide update in 1-2 weeks for the progress
to make the report more informative and useful.

Thanks, that link has all the info needed to reproduce AFAICT, as long
as you make sure to send it to a mailing list which gets archived by
lore.kernel.org - otherwise the redirection won't work.

Thx.
