函数名称：lock_pin_lock

函数原型：struct pin_cookie lock_pin_lock(struct lockdep_map *lock)

返回类型：struct pin_cookie

参数：

类型参数名称
struct lockdep_map *lock
4532  cookie等于NIL_COOKIE
4535  如果此条件成立可能性小(为编译器优化)(lockdep_recursion)则返回:cookie
4538  raw_local_irq_save(flags)
4539  Check whether we follow the irq-flags state precisely:
4541  lockdep_recursion等于1
4542  cookie等于__lock_pin_lock(lock)
4543  lockdep_recursion等于0
4544  raw_local_irq_restore(flags)
4546  返回:cookie
