FIX ME locking is implemented?

I am wondering why the fix me in the code below still exists as this code is clearly being locked properly with a spin lock on the lock related to the created linked list in this code.

/* FIXME: Locking */
spin_lock_bh(&ar->list_lock);

list_for_each_entry(vif, &ar->vif_list, list) {
	if (vif->nw_type == ADHOC_NETWORK ||
 			action != HTC_SEND_FULL_DROP) {
                        spin_unlock_bh(&ar->list_lock);

                         set_bit(NETQ_STOPPED, &vif->flags);
                         netif_stop_queue(vif->ndev);

                         return action;
              }
        }
        spin_unlock_bh(&ar->list_lock);
