Friends,
I am doing my final year project on filesystem RAIF(Redundant array of independent file systems). I want to study the basic design of file system using ramfs. I am inserting functions step by step & also inserting printk , so that i can find the flow of particular commands like mkdir or functions like open,read etc. Even though i can use these functions from fs/inode.c i don't want to disturb kernel code every time, which will require to compile kernel every time. By using only specific code in my file i can precisely understand the working. But now i am stuck at this point. Do u know any better solution? Plz convey me.

Hi,
You added 2 functions alloc_inode and new_inode from
/usr/src/linux/fs/inode.c to /usr/src/linux/fs/ramfs . You add
alloc_inode because new_inode requires it ok.
but why you want to do that as i think already new_inode in
/usr/src/linux/fs/ramfs/inode.c calling its function definition from
/usr/src/linux/fs/inode.c
so you can directly recompile kernel with ramfs support(which is
default in 2.6.14.3) and insert module.
regards,
Parag.
