函数名称：lock_unpin_lock

函数原型：void lock_unpin_lock(struct lockdep_map *lock, struct pin_cookie cookie)

返回类型：void

参数：

类型参数名称
struct lockdep_map *lock
struct pin_cookiecookie
4571  如果此条件成立可能性小(为编译器优化)(lockdep_recursion)则返回
4574  raw_local_irq_save(flags)
4575  Check whether we follow the irq-flags state precisely:
4577  lockdep_recursion等于1
4578  __lock_unpin_lock(lock, cookie)
4579  lockdep_recursion等于0
4580  raw_local_irq_restore(flags)
