Yep, these books might work. But, I suggest you read up on the VFS concept first. Understanding the Linux Kernel does a good job. Then I suggest you read the VFS code. The people here can help you. That's just my personal opinion though. I was dealing with the mm system some time ago, and I found that reading the code was far more informative than a book, especially because books tend to get dated.
