hi,
i am new in linux kernel development field. I am trying to understand the kernel memory management functions and codes. Any suggestion regarding this topic would be very helpful for me.

thanks in advance.

Good luck.
Best sites to start are probably linux-mm.org and kernelnewbies.org

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.

You might find the Interactive Kernel Map useful: http://www.makelinux.net/kernel_map/

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

OTOH

• 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.
