So, you want to write a kernel module. You know C, you ve written a few normal programs to run as

processes, and now you want to get to where the real action is, to where a single wild pointer can wipe out

your file system and a core dump means a reboot.

What exactly is a kernel module? Modules are pieces of code that can be loaded and unloaded into the kernel

upon demand. They extend the functionality of the kernel without the need to reboot the system.
