Hi,

Welcome to LQ!

'Anatomy of the Linux kernel' is a good resource and would be a start. Then look at 'Linux Kernel' section of 'Slackware-Links' for kernel related links.

How to Ask Questions the Smart Way' would be one link you should also look at to help us to help you in the future.

Plus do a search here on LQ as this subject has been addressed many times.

Just a few more links to aid you;
Linux Documentation Project
