Dear All,Can anybody please help me how does dentry does path resolution. I want to undersatnd the whole process in detail. Any link or comments are most welcome.
I found following useful :-
Just asking for my understanding,Dentry maintains a relationship between file object & inode for path name lookup ? Is it right ?
A dentry is an object with a string name (d_name), a pointer to an inode
(d_inode), and a pointer to the parent dentry (d_parent).
(d_inode), and a pointer to the parent dentry (d_parent).
If the pathname is /home/krishna/myfile, how it will be resolve ?
If I am not wrong we will start from "/" and at each level we will look into the dentry cache using "d_lookup" function to find a name "file -> inode" mapping.
If we don't find in the cache then with "do_lookup" function we will try to find out the inode for the file.
