DESCRIPTION

       Probe points for probing irq handler execution, softirqs, workqueues,etc

       workqueue.create
	      probes creation of a new workqueue

	      Arguments:

	      wq_thread
		 task_struct of the workqueue thread.

	      cpu
		 cpu for which the worker thread is created.

       workqueue.insert
	      probes queuing of work on a workqueue.

	      Arguments:

	      wq_thread
		 task_struct of the workqueue thread.

	      work
		 work_struct* being executed.

	      work_func

	      Arguments:

	      wq_thread
		 task_struct of the workqueue thread.

	      work
		 work_struct* being executed.

	      work_func
		 pointer to handler func.

       workqueue.destroy
	      probes destruction of each worker thread of each cpu for a workqueue.

	      Arguments:

	      wq_thread
		task_struct of the workqueue thread.

       irq_handler.entry
