11   This function creates a directory in debugfs with the given name.

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