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.
