So I've actually been complaining about the link tags for years: [1]
[2] [3] [4].

In fact, that [4] from 2022 is about how people are then trying to
distinguish the *useful* links (to bug reports) from the useless ones,
by giving them a different name ("Buglink:"). Where I was telling
people to instead fix this problem by just not adding the useless
links in the first place!

Anyway, I'm a bit frustrated, exactly because this _has_ been going on
for years. It's not a new peeve.

And I don't think we have a good central place for that kind of "don't do this".

Yes, there's the maintainer summit, but that's a pretty limited set of people.

I guess I could mention it in my release notes, but I don't know who
actually reads those either..

So I end up just complaining when I see it.

And yeah, I will take some of the blame for people doing the useless
Link. Because going even further back, people were arguing for random
"bug ID" numbers. Go search lkml, and you'll find discussions about
having UUID's in the commits, and I said that no, we're not doing
that, and that a "Link:" tag to something valid is a good alternative,
and I even mentioned a link to the submission. So that could be seen
as some kind of encouragement - but it was more of a "no, we're *NOT*
doing random meaningless UUIDs".

I did go back and look in the git archives. The oldest link we have in
the kernel git tree is from 2011. Guess what? That email has had over
fourteen years to get more information associated with it on the
mailing list, but no.

That link has _zero_ new information that would be relevant outside
the commit that references it (f994d99cf140: "x86-32, fpu: Fix FPU
exception handling on non-SSE systems").
