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.

Why 2.4.18? Can you plea
First of all...
Can you please explain the why of your subject?
You're pretending to build RFS on 2.4.18? Why?
why RFS
that my project.
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

Missed the point
Well, my question was why 2.4.18...

why 2.4.18-14
hi,
sorry for that. i dont have any specific reason for using that verson. just i am new to linux so doing that with whatever resources i have.
well, i have back Question. does it make any big difference if i use diff verson. i am not sure. well, i can ue diff kernel if you suggest me why and how.
any way. waiting for your reply for file system stuff.
why 2.4.18-14
hi,
sorrry for that. :-(
well, i dont have any specific reason for using 2.4.18-14. just i am new to linux and this system programming stuff, and i have to do that FS in short time. so i a using resources taht i have rigth now.
any way, i have back Question. does it make bog diff if i use diff kernel ? i am new to linux so asking u. i can use diff kernel if u suggest me .
anyway, i am waiting for yout reply regarding FS.
thanks.

If the idea is to do a kernel
If the idea is to do a kernel patch to add that FS, then yes, the patch will be kernel-deppendent.
I recommend you to use the last kernel, either the stable branch (2.4) or unstable (2.6), now that decision is up to you.
Files i have to deal with ?
hi,
Thanks for reply. can u tell me what files i have to deal with ? i am new to linux. what i have to do as a first step to proceed my project ?

First study VFS implementation, and only then start working on your own...
