FWIW, linux-wireless developers maintain a generic compat tree used
for backporting wireless drivers:
http://git.kernel.org/?p=linux/kernel/git/mcgrof/compat.git;a=summary
I suppose it might be useful to share this between linux-wireless
and linux-media?
(It is used together with three other trees to autobuild
the compat-wireless releases.
http://wireless.kernel.org/en/users/Download
It works like that:
- compat.git: generic backporting layer
- compat-wireless-2.6.git: build system
- compat-user.git: autobuild scripts called via cron
- wireless-testing.git: linux-wireless development tree
(wireless-testing.git is based on latest stable kernel but with
the wireless code from linux-next)
compat-wireless releases are not meant for development, but
they can be used as a build system together with a wireless-testing.git
tree and a few symlinks.)
