Type:int

Parameter:

403  When Not break_test() cycle
404  g_buffer_reset - reset a ring buffer*@buffer: The ring buffer to reset all cpu buffers
406  If consumer Then
407  wake_up_process - Wake up a specific process*@p: The process to be woken up.* Attempt to wake up the nominated process and move it to the set of runnable* processes.* Return: 1 if the process was woken up, 0 if it was already running.
408  wait_for_completion: - waits for completion of a task*@x: holds the state of this particular completion* This waits to be signaled for completion of a specific task. It is NOT* interruptible and there is no timeout.* See also similar routines (i
411  ring_buffer_producer()
412  If break_test() Then Go to out_kill
415  trace_printk("Sleeping for 10 secs\n")
416  set_current_state(TASK_INTERRUPTIBLE)
417  If break_test() Then Go to out_kill
419  schedule_timeout - sleep until timeout*@timeout: timeout value in jiffies* Make the current task sleep until @timeout jiffies have* elapsed
422  out_kill :
423  set_current_state() includes a barrier so that the write of current->state* is correctly serialised wrt the caller's subsequent test of whether to* actually sleep:* for (;;) {* set_current_state(TASK_UNINTERRUPTIBLE);* if (!need_sleep)* break;* (Used in tsk->state: )
424  If Not kthread_should_stop - should this kthread return now?* When someone calls kthread_stop() on your kthread, it will be woken* and this will return true. You should then return, and your return* value will be passed through to kthread_stop(). Then wait_to_die()
427  Return 0
