- * This is used to release a work item that has been initialised with automatic

- * 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.

- * 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.
