A Dkref.rst231 上面的例子也可以用kref_get_unless_zero()来优化，方法如下::
239 if (!kref_get_unless_zero(&entry->refcount))
262 kref_get_unless_zero被封装在查找表中的同一关键部分，否则kref_get_unless_zero
263 可能引用已经释放的内存。注意，在不检查其返回值的情况下使用kref_get_unless_zero
264 是非法的。如果你确信（已经有了一个有效的指针）kref_get_unless_zero()会返回true，
270 函数kref_get_unless_zero也使得在上述例子中使用rcu锁进行查找成为可能::

A Dkref.rst237 The above example could also be optimized using kref_get_unless_zero() in
246 if (!kref_get_unless_zero(&entry->refcount))
269 it's important that kref_get_unless_zero is enclosed in the same critical
271 otherwise kref_get_unless_zero may reference already freed memory.
272 Note that it is illegal to use kref_get_unless_zero without checking its
274 kref_get_unless_zero() will return true, then use kref_get() instead.
279 The function kref_get_unless_zero also makes it possible to use rcu
