函数名称：tracing_sched_wakeup_trace

函数原型：static void tracing_sched_wakeup_trace(struct trace_array *tr, struct task_struct *wakee, struct task_struct *curr, unsigned long flags, int pc)

返回类型：void

参数：

类型参数名称
struct trace_array *tr
struct task_struct *wakee
struct task_struct *curr
unsigned longflags
intpc
408  call等于event_wakeup
411  buffer等于buffer
413  event等于trace_buffer_lock_reserve(buffer, TRACE_WAKE, entry的长度, flags, pc)
415  如果非event则返回
417  entry等于g_buffer_event_data - return the data of the event*@event: the event to get the data from
418  prev_pid等于进程ID
419  prev_prio等于prio
420  prev_state等于task_state_index(curr)
421  next_pid等于进程ID
422  next_prio等于prio
423  next_state等于task_state_index(wakee)
424  next_cpu等于task_cpu(wakee)
426  如果非call_filter_check_discard(call, entry, buffer, event)则trace_buffer_unlock_commit(tr, buffer, event, flags, pc)
