Mhhh something much simpler:

Use the current development model between 2.6.N and 2.6.N+1. This
means the current dev model would be used like NOW, BUT changing the
versioning scheme in a way which reflects the 6months release plans.
TRYING TO EXPLAIN THINGS BETTER: You could skip the version scheme
change and do something like:

EXAMPLE:

2.6.14 - ok let's plan 3/4/whatever releases in the next 6 months with
those major new features:
 - A
 - B
 - C

then: .15, .16 like every 2.6 kernel, same dev model, same everything
(erhm not every just like the latest releases, ok)
.18 would be MAINLY stabilization: no device model changes, no
networking change, and so on (but i think it would be ok new drivers
since they cant be disabled or simply not used)

and .19 would come out  months after the .14 release

it's not a stable/devel or 2.6/2.7 or better 2.4/2.5 scheme (even a
2.6/2.7 scheme almost exists with main tree/-mm tree atm) or old stuff
under a different point of view BUT it's the SAME current dev model
applied to every release EXCEPT for the last one BEFORE the 6months
timeline.

what does it means: no one says nothing is unacceptable, it means
things could be better for distros/users/external kernel projects by
doing something that could be called a two-layers model:

--------------------
Linus & co. "hey, let's write down the major features for the next 6
months and plan things a little"
--------------------
Other kernel developers "I would like to get in X, Y and Z. Let's do
it 2.6.x style."
--------------------

The changed versioning scheme just reflects the 6months release ciclye
idea. fullstop.

trying to clarify again:

every 2.6.N.x release would be the SAME as a 2.6.x release. The entire
6months cycle puts in some time/features/stability boundaries on top
of the existent model. Finally, those stability boundaries would be
planned every 6months assuring the best fit of the model with
developers, distros and users needs.


hope I clarified,
Michele
