自旋锁：
在多核处理器系统中,系统不允许在不同的CPU上运行的内核控制路径同时访问某些内核数据结构,
在这种情况下如果修改数据结构所需的时间比较短，那么信号量（参考信号量）是低效的。
这是系统会使用自旋锁，当一个进程发现锁被另一个进程锁着时，他就不停”旋转”，执行一个紧凑的循环指令直到锁被打开。
但是这种自旋锁在单核处理器下是无效的。当内核控制路径试图访问一个上锁的数据结构，他就开始无休止的循环。因此，
内核控制路径可能因为正在修改受保护的数据结构而没有机会继续执行，也没有机会释放这个... |

互斥锁：
互斥锁（Mutex）是在原子操作API的基础上实现的信号量行为。互斥锁不能进行递归锁定或解锁，
能用于交互上下文但是不能用于中断上下文，同一时间只能有一个任务持有互斥锁，而且只有这个任务可以对互斥锁进行解锁。
当无法获取锁时，线程进入睡眠等待状态。
互斥锁是信号量的特例。信号量的初始值表示有多少个任务可以同时访问共享资源，如果初始值为1，表示只有1个任务可以访问，
信号量变成互斥锁（Mutex）。但是互斥锁和信号量又有所区别，互斥锁的加锁和解锁必须在同一线程里对应使用，所以互斥锁只能用于线程的互斥；
信号量可以由一个线程释放，另一个线程得到，所以信号量可以用于线程的同步。
