 Note that I'm not a professional kernel hacker, and I don't write code for the kernel at work. It's just a hobby. I just like low-level stuff, and it is interesting for me to see how these things work. So if you notice anything confusing, or if you have any questions/remarks, ping me on twitter [0xAX](https://twitter.com/0xAX), drop me an [email](anotherworldofworld@gmail.com) or just create an [issue](https://github.com/0xAX/linux-internals/issues/new). I appreciate it. All posts will also be accessible at [linux-internals](https://github.com/0xAX/linux-internals) and if you find something wrong with my English or post content, feel free to send pull request.

We will not see description and explanation of all fields of kernel setup header, we will get back to it when kernel uses it.
