Good luck.
Best sites to start are probably and

There isn't a lot of good (current) overview material out there (that I could find). Diving into the code drove me to drink - the code is convoluted and a reasonable amount is (in-line) assembler. Not an easy assignment, although in my case it was a side-issue to what I was really looking for at the time.

There is a book available called 'Understanding the Linux Virtual Memory Manager' by Mel Gorman. part of the Bruce Perens/Prentice-Hall Open Source series There are a number of pluses and minuses
  • It is free, as a pdf
  • If you are lucky, if you look on distrowatch, you'll get a link from which to download it; otherwise a search?
  • Easier and better organised (for this purpose) than the RTFS solution
  • It is a little dated (2.6 just...the details will have had some changes, but the fundamentals will be the same)
  • It is not exactly a trivial, fun, read....but then it wouldn't be

I don't know if there is a more up-to-date, paid for/dead-tree-ware version available, but there might be.
