Another shameless plug for me:

Short version to save you reading of my spam:
Let's make 2.7 what 2.6 is now (a relatively stable kernel that gets
relatively stable feature enhancements continuously), rather than what
2.5 was (a hell of a lot of patches and then a hell of a lot of
debugging), and make 2.6 more restrictive than 2.4 in that it should be
strictly bugfixes (including security bugs) and no backported drivers or

I read a page about open source software development once, I don't
remember if it was an article or a book or what; but it said something
I've held to heart for a while: Open source projects tend to follow the
poorly designed development model of alternating between a "stable" and
an "unstable" branch, when it's possible to simply perpetually add
stablized, debugged features straight to mainline after they've been
developed independently on the side.

It is apparent that what we have here is exactly what the author
suggested in place of the stable/unstable cycle; it is also apparent
that this is a naiive model not because it becomes difficult to avoid
bugs, but because it becomes difficult to actually develope on the side
with all of the changes happening to mainline. By combining both
models, a balance is met.

This same model can be implemented as a meta-model (or something) if the
external projects chose on their own which versions to freeze at. This
creates a problem, however, as patches for these projects become
distributed across ranges of versions. Consider having a development
driver for 2.6.7 for an ADSL card; a development driver for 2.6.5 for a
network card; and a development DRM driver for 2.6.10 for a particular
video card. The unfortunate soul having all three of these pieces of
hardware is quite SOL.

On the other hand, there are those who simply get fed up chasing the
volatile codebase of mainline, ad simply wait for it to stabalize.
Unless you throw them their bone, they won't get any work done; this is
not only their problem, but their users' as well.
