There's no single answer - multiple files can have the same inode number
(they're called hard links).  Finding which filesystem they are on
involves walking through the mount table..

Hi,

Actually, what I meant with this was, suppose I have a file name, how do I get the inode for that? And also suppose I have the inode number, how do I get the complete object of that inode for use and manipulation?

Thanks in advance

Sumit

If you have a filename, stat(2); see also lstat(2) and fstat(2).

Hi,

You can give a look on user_path_walk() and user_path_walk_link() (see 
include/linux/fs.h), given you have the pathname. 
Given you have the inode number, you can get one of the references to it by 
using d_path() (see include/linux/sched.h). I just don't know how it works  
when there is multiple references to the same inode number (hard links).

Sorry, I mean the struct file.
