File System Development (HELP!)

Hi gurus,

I am researching for a project for university as I wish to develop my own kernel driver for NTFS. I am struggling with some of the specifics though.

I know how NTFS works extensively and I am aware of the structure within freeBSD for the system interaction with VNODE (i think).

What im not sure how to model/program is the interaction between the filesystem and the system calls. Im not sure where it fits in in the grand jigsaw puzzle of it all. I have read the design and implementation of FreeBSD a couple of times now and it along with the rest of the web, are holding their cards close to their chest when it comes to file system kernel driver development.

I dont need a solution, just a pointer to the information that will enable me to build my own solution (books, webpages e.t.c.).

Many Thanks,

Steve

The biggest problem is that NTFS is a closed source system. The NTFS filesystem specification is a trade secret. Hence you will have difficulty finding information about it.

You can also take a look at the sysutils/fusefs-ntfs solution.
 
I am happy with the constructs of NTFS. I have looked at alot of the available documentation around it.

What I am still confused about is the structuring of the drivers for all of freeBSD's filing systems, not just NTFS. I have looked at the drivers for some of the other filing systems and its hard to determine whats going on.

Some of them have a different number of files and some of them outline different functions, others are the same. Are there specific named functions relating to similar system calls?
