This function renames a file/directory in debugfs. The target must not
exist for rename to succeed.

This function will return a pointer to old_dentry (which is updated to
reflect renaming) if it succeeds. If an error occurs, <code class="constant">NULL</code> will be
returned.
</p><p>
If debugfs is not enabled in the kernel, the value -<code class="constant">ENODEV</code> will be
returned.
