Who Should Read This

This document is for people who want to write kernel modules. Although I will touch on how things are done in the kernel in several places, that is not my purpose. There are enough good sources which do a better job than I could have done.

This document is also for people who know how to write kernel modules, but have not yet adapted to version 2.2 of the kernel. If you are such a person, I suggest you look at appendix A to see all the differences I encountered while updating the examples. The list is nowhere near comprehensive, but I think it covers most of the basic functionality and will be enough to get you started.

The kernel is a great piece of programming, and I believe that programmers should read at least some kernel source files and understand them. Having said that, I also believe in the value of playing with the system first and asking questions later. When I learn a new programming language, I don't start with reading the library code, but by writing a small `hello, world' program. I don't see why playing with the kernel should be any different.
