类型参数名称
struct notifier_block *nb
unsigned longevent
void *data
57  mod等于data
58  struct gcov_info * info = NULL
59  struct gcov_info * prev = NULL
61  如果event不等于 Going away. 则返回:Suits me
63  mutex_lock( & gcov_lock)
66  当info等于gcov_info_next(info)循环
67  如果gcov_info_within_module(info, mod)则
68  gcov_info_unlink(prev, info)
69  如果gcov_events_enabled则Callback to create/remove profiling files when code compiled with* -fprofile-arcs is loaded/unloaded.
71  否则prev等于info
75  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.
