need some help on File System

[chaitanya Ralegaonkar]

I am Chaitanya A. Ralegaonkar , student of VIT , Pune.
I am a begineer in the area of file system and interested in developing the Stackable FS, so need some help regarding it.

I read about FiST ( a paper by Dr. Erez Zadok ; for developing stackable file system ),vfs and concepts of file system from Bach. What else I should read to work in this field.

Thanking all in anticipation,
Chaitanya
