Thanks Jan for the response.

>struct dentry *foooobar = lookup_one_len("/foo/bar", current->fs->root);

But that gives me a dentry, where as file object is still not reachable. 

Question: I am currently using a function called fs.h/dentry_open which takes a "dentry", "vfsmount" object  and flag (usually RW i.e. 2), and gives me the file object. with  your suggested method, vfsmount is still not available. In this regard, any idea about a function, which gives directly the file object instead of dentry will be highly appreciated. 

OR,  (Kindly see the code below), i need some thing for "missing vfsmount".

    struct dentry *foooobar = lookup_one_len("/foo/bar", current->fs->root);
    struct file *file1 = dentry_open(foooobar, "missing vfsmount here",2)

Thanks,
JG
