Re: New Linux Development Model

Hi, huh...

... don't you have a real name? Posting as "hostmaster" may impress
teenagers, but over there we tend to prefer people with real names.

Your problems seem to be very specific to wireless networking, right?
Blaming the whole development model because one area seems to have
problems is a bit awkward, don't you think? Report to the persons
responsible for that area and/or specific driver, tell them about the
problem, they'll surely listen to you and improve the process if
possible.

Also, the point you mention for the 2.6.13 -> 2.6.14 transition is
irrelevant with regards to the development model. With a different
development model, the driver wouldn't have been added at all. This
wouldn't have made any difference for you as far as I can see.

Third party drivers don't work, and you complain to us. What's the
point?

You should read this document:
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/stable_api_nonsense.txt

We don't care. It's their choice, not ours.

It is. If they are not happy with that, they simply get their code
integrated into the main Linux tree, and get to work with us rather
than apart on their own. It's easier for us, it's easier for them,
and it's easier for the users. Everyone benefits.

Yet you don't propose anything to improve it?
