15   This function creates a symbolic link with the given name in debugfs that
16   links to the given target path.
17   </p><p>

19   This function will return a pointer to a dentry if it succeeds.  This
20   pointer must be passed to the <code class="function">debugfs_remove</code> function when the symbolic
21   link is to be removed (no automatic cleanup happens if your module is
22   unloaded, you are responsible here.)  If an error occurs, <code class="constant">NULL</code> will be
23   returned.
24   </p><p>
25
26   If debugfs is not enabled in the kernel, the value -<code class="constant">ENODEV</code> will be
27   returned.
