Hi All,

I had a module which used the path_lookup function to print the details of any file's inode. I now want to rewrite that module in order to show some juniors how to write some code in kernel.

I am using 3.4.6 kernel, I tried finding out path_lookup but google showed that it has been removed.

I tried the following code then which did not work

.
.
.
dentry = kern_path_create(AT_FDCWD, filename, &path, 1);

if (IS_ERR(dentry)) {
              printk("Failed to obtain the dentry");
               return;
       }

its not returning dentry

I again tried after seeing the implementation of vfs_stat function

user_path_at(AT_FDCWD, filename, lookup_flags, &path);

but this also fails.

I am using a proc interface to pass the filename, and copying the filename into a kernel buffer.

How can I get a copy of vfs inode for a file name.
