> It outlines the problems with Linux kernel development and questionable

I have to step in and disagree here....

Linux is not about who writes the code.

Linux is about getting the best solution for a problem. Who wrote which
line of the code is irrelevant in the big picture.

that often means that multiple implementations happen, and that the a
darwinistic process decides that the best solution wins.

This darwinistic process often happens in the form of discussion, and
that discussion can happen with words or with code. In this case it
happened with a code proposal.

To make this specific: it has happened many times to me that when I
solved an issue with code, someone else stepped in and wrote a different
solution (although that was usually for smaller pieces). Was I upset
about that? No! I was happy because my *problem got solved* in the best
possible way.

Now this doesn't mean that people shouldn't be nice to each other, not
cooperate or steal credits, but I don't get the impression that that is
happening here. Ingo is taking part in the discussion with a counter
proposal for discussion *on the mailing list*. What more do you want??
If you or anyone else can improve it or do better, take part of this
discussion and show what you mean either in words or in code.

Your qualification of the discussion as a elitist takeover... I disagree
with that. It's a *discussion*. Now if you agree that Ingo's patch is
better technically, you and others should be happy about that because
your problem is getting solved better. If you don't agree that his patch
is better technically, take part in the technical discussion.
