Kernel docs are written for consumption by other kernel hackers, not lay people.
 Keep that in mind.  I can get you the information you seek.  Digesting it is up
to you:

http://linux-mm.org/LinuxMM
http://www.phptr.com/content/images/0131453483/downloads/gorman_book.pdf

The ebook is 700+ pages, about 8.5MB.  The title is:
"Understanding the Linux Virtual Memory Manager"

Curiously, why did you ask here instead of lkml?  That should be every person's
natural target for such a question.
