+ *   terminate  - kill the process, i.e. all threads in the group,

+ *   stop       - stop all the threads in the group, i.e. TASK_STOPPED state

- * work_release - Release a work item under execution
- * @work: The work item to release
- *
- * This is used to release a work item that has been initialised with automatic
- * release mode disabled (WORK_STRUCT_NOAUTOREL is set).  This gives the work
- * 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.
+ * work_clear_pending - for internal use only, mark a work item as not pending
+ * @work: The work item in question
