you need to keep reading the book and look at source files it points you to.
use ctags/csope to navigate through the code.
Besides read more, look at kernelnewbies.org site for more information.
google a little before you ask these questions.

In the end the Linux kernel is just a big project written in C.
Instead of asking what files do you need to understand. You should ask
yourself what subsystem do you want to learn?

Focus on functionality and browse the code to understand. As others
pointed before there are lots of good books that will give you a high
overview of the kernel.

The first book that I recommend reading is Linux kernel development by
Robert Love, but only if you have already read a book on operating
system concepts. The best book for me is Andrew Tanenbaum's Modern
Operating Systems.

Hope it helps,

Hi Venkateswarlu,

For Better understanding of do_fork you need to see the following link

http://elinux.org/Kernel_Function_Trace

This link tell you what all kernel functions?are getting called when you fork 
from userspace.

with regards
Anand Moon

[abhijeet tripathi]

Venkat,

You can use?http://lxr.linux.no/?to browse for kernel source. It's an online tool and you can directly see the usage, declaration, definition of functions, structures, etc.
My $.02
