Module Programming
Where can I follow the modifications under the main functions of linux kernel programming between versions of kernerl?
I am asking that because I have some work on that area and I want it to be portable to every kernel versions.

The authoritative reference for Linux device drivers is Rubini and Corbet's book "Linux Device Drivers". You should buy your own copy but there is an online copy available:

Linux device drivers are not guaranteed to be portable between kernel versions, however they are usually platform-independent.
Cheers!

Well you can't be "portable to every kernel version", but you can design your modules so that they will compile and run on every version that supports modules.
The easiest thing is to try to compile your module, designed for an older version, using a newer version of kernel headers. You can then "fix" things that don't compile. You fix them inside some compiler conditionals so they are not "fixed", hense broken, for previous versions.
If you have a lot of modules, then you probably should make a 'configure' program or script that sets the proper conditionals in some dynamic header file, based upon the kernel version.
