35 要使用kref，请在你的数据结构中添加一个，如::
41 struct kref refcount;
46 kref可以出现在数据结构体中的任何地方。
51 你必须在分配kref之后初始化它。 要做到这一点，可以这样调用kref_init::
60 这将kref中的refcount设置为1。
65 一旦你有一个初始化的kref，你必须遵循以下规则:
72 如果你已经有了一个指向kref-ed结构体的有效指针（refcount不能为零），你
80 在没有已经持有有效指针的情况下获得一个kref-ed结构体的有效指针，那么在没
83 3) 如果代码试图获得对一个kref-ed结构体的引用，而不持有一个有效的指针，它必
