+ * function the opportunity to grab auxiliary data from the container of the
+ * work_struct before clearing the pending bit as the work_struct may be
+ * subject to deallocation the moment the pending bit is cleared.
+ *
+ * In such a case, this should be called in the work function after it has
+ * fetched any data it may require from the containter of the work_struct.
+ * After this function has been called, the work_struct may be scheduled for
+ * further execution or it may be deallocated unless other precautions are
+ * taken.
+ *
+ * This should also be used to release a delayed work item.
