Type:void
Parameter:
| Type | Parameter | Name | 
|---|---|---|
| struct trace_kprobe * | tk | |
| struct pt_regs * | regs | |
| struct trace_event_file * | trace_file | 
| 1182 | call = trace_probe_event_call( & tp) | 
| 1184 | WARN_ON(call != event_call) | 
| 1189 | local_save_flags(irq_flags) | 
| 1190 | pc = We mask the PREEMPT_NEED_RESCHED bit so as not to confuse all current users* that think a non-zero value indicates we cannot preempt. | 
| 1193 | size = size of entry + trace entry size + dsize |

| 1198 | If Not event Then Return | 
| 1201 | entry = g_buffer_event_data - return the data of the event*@event: the event to get the data from | 
| 1202 | ip = location of the probe point |
