Feeds unlock tab

I had one of my feeds freeze up and I can't unlock it. I did some searching and found a function for adding an unlock tab form this page:

http://drupalcontrib.org/api/drupal/contributions!feeds!feeds.pages.inc/function/feeds_unlock_tab_form/7

<?phpfunction feeds_unlock_tab_form($form, &$form_state, $importer_id, $node = NULL) {  if (empty($node)) {    $source = feeds_source($importer_id);    $form['#redirect'] = 'import/' . $source->id;  }  else {    $importer_id = feeds_get_importer_id($node->type);    $source = feeds_source($importer_id, $node->nid);    $form['#redirect'] = 'node/' . $source->feed_nid;  }  // Form cannot pass on source object. $form['#importer_id'] = $source->id; $form['#feed_nid'] = $source->feed_nid; $form['source_status'] = array('#type' => 'fieldset', '#title' => t('Status'), '#tree' => TRUE, '#value' => feeds_source_status($source), ); $form = confirm_form($form, t('Unlock this importer?'), $form['#redirect'], '', t('Delete'), t('Cancel'), 'confirm feeds update'); if ($source->progressImporting() == FEEDS_BATCH_COMPLETE && $source->progressClearing() == FEEDS_BATCH_COMPLETE) {   $form['source_locked'] = array('#type' => 'markup', '#title' => t('Not Locked'), '#tree' => TRUE, '#markup' => t('This importer is not locked, therefore it cannot be unlocked.'),   );   $form['actions']['submit']['#disabled'] = TRUE;   $form['actions']['submit']['#value'] = t('Unlock (disabled)'); } else {   $form['actions']['submit']['#value'] = t('Unlock'); } return $form;} ?>

So I know it goes in the feeds.pages.inc but not sure how to implement this. Can someone please point me in the right direction, thanks!
