building new File System
 

Hello everyone,
I am new to this group and new to linux kernel also. so please do consider my Questions. i am really interested in linux at system level
I am working on one project. I have to build new filesystem (called Reservation fiel system, which will provide better QoS) on VFS. i am so much confused as i am really new to this thing. i tried understanding VFS system and data structure.
now my question. from where i should star? i want to make one simple dummy file system code and what to test it. can anybody make my concep clear. what i should do as a first step. what files i have to interact with ?
i am waitinf gor your replies. thakyou very much.

i would like to add more detail in that....
What it will basically do is....
it will contain tree structure and will have 2 types of nodes.
1.. Sheduler node (say SN)
2... Queuing node (say QN)

there will be different type of queuing node and thay will be assigned weights based on priority. any request form OS will be queued in one of those QN (based on priority)
task of SN to shedule those QN's request.
basiccaly we are going to have our own QoS on linux. so tat will be done by RFS (which will be based on VFS as per described by my professor).
if you want i can email u whoel paper about RFS if u give me your email address.
i hope u got what i want to do.. i want to implement RFS using VFS...
i am waitin for your reply. thanks for getting inteest in my topic
