You are missing the point.

The only thing we can do is to teach people that the Makefile version
isn't too important, and that it really doesn't tell very much.

Trying to tweak it to make it somehow "more meaningful" is a BAD THING,
because it continues to spoon-feed people a lie.

The cake is a lie. In between kernel versions, you can't rely on the
Makefile. You should teach yourself (and others) THAT, rather than trying
to teach people to believe the lie even more.

Once you start believing the lie, suddenly all the subtrees will start
thinking that now _their_ kernel versions are bad, so now they'll start to
want to make the same idiotic changes to their Makefiles, or maybe
they'll decide that they don't want to pull tagged releases, but the "one
after the tag so that they'll get the updated Makefile".

And even if they don't do that idiocy, the whole "the version number is
meaningful outside of releases" thing leads to brain damage.

Yes, I could live with that. If you're compiling from a git tree, we migth
as well show the real version.

It's the "let's make that meaningful and misleading number be even _more_
misleading by making people think it has meaning" magical thinking that I
hate.

It's wrong, and it leads people to believe in things that aren't true. I
refuse to cater to that kind of wrongheaded thinking.

I'd much rather screw up the version number entirely and add a _random_
number to it (so that the Makefile would say "2.6.18" after I have
released 2.6.32) just so that people would be forced to _understand_ that
the version number isn't as meaningful as you seem to think it is.

For example, let's take Arjan's request, that kerneloops should get -rc0.

Think about that for a few minutes. Really THINK about it. What happens?

[ Spend some time really thinking here. ]

What about people like all the networking guys who are running their
development kernels that haven't been merged yet? Their kernels won't say
-rc0. Are you going to ask them to do it too?

Or would you be better off teaching kerneloops about local versions?
