Thank you for the new proposition.

I like your approach of forcing people to use the "Closes:" tag, I
didn't think it would have been OK. I will wait a bit before sending a
v4 just to get more feedback about that.

The good thing with this approach is that it makes things clear. The
"Closes:" tag is then no longer an alternative to "Link:" but a
different tag, e.g. to be used after "Reported-by" as you did in your patch.

I guess as any warnings from checkpatch.pl, it needs to be interpreted,
e.g. if multiple bugs are reported in the same report as Conor mentioned.

Cheers,
Matt
