initialize operation

基本解释

You create and initialize a mutex in one operation through the DEFINE_MUTEX macro.
可以通过 DEFINE_MUTEX 宏使用一个操作创建和初始化互斥锁。
Notice that when we invoke the operation, we don't bother to initialize either the owner or balance parameters.
注意，当我们调用这个操作时，无需初始化 owner 或 balance 参数。
If the first reference to a class C occurs during a time-critical operation, then the time to resolve, verify, load, and initialize C might cause that operation to take longer than expected.
如果对一个类 C 的首次引用发生在时间关键型操作期间，那么解析、验证、加载和初始化 C 的时间可能导致执行操作的时间比预期更长。
