函数名称：bpf_get_raw_tracepoint_module

函数原型：static struct bpf_raw_event_map *bpf_get_raw_tracepoint_module(const char *name)

返回类型：struct bpf_raw_event_map

参数：

类型参数名称
const char *name
36  struct bpf_raw_event_map * btp, * ret = NULL
40  mutex_lock( & bpf_module_mutex)
42  以i小于num_bpf_raw_events循环
43  btp等于bpf_raw_events[i]
44  如果非字符串比较则
45  如果判断模块是否处于活动状态则ret等于btp
47  转到:out
51  out :
52  mutex_unlock - release the mutex*@lock: the mutex to be released* Unlock a mutex that has been locked by this task previously.* This function must not be used in interrupt context. Unlocking* of a not locked mutex is not allowed.
53  返回:ret
