Once in spin::once - Rust.

当spinOnce函数被调用时，spinOnce就会调用回调函数队列中第一个callback函数，此时callback函数才被执行，然后等到下次spinOnce函数又被调用时，回调函数队列中第二个callback函数就会被调用，以此类推。所以，这会有一个问题。因为回调函数队列的长度是有限的，如果发布器发送数据的速度太快，spinOnce函数调用的频率太少，就会导致队列溢出，一些callback函数就会被挤掉，导致没被执行到。而对于spin函数，一旦进入spin函数，它就不会返回了，相当于它在自己的函数里面死循环了。只要回调函数队列里面有callback函数在，它就会马上去执行callback函数。如果没有的话，它就会阻塞，不会占用CPU。.

作为SMP系统中的一个高频操作，spinlock的性能毫无疑问会影响到整个系统运行的性能，所以，从ticket spinlock到MCS lock，再到qspinlock，见证了内核开发者对其一步步的优化历程。在优秀的性能背后，是对每一行代码的反复推敲和考量，最终铸就了qspinlock精妙但并不简单的实现过程。也许，它还有优化的空间…… 至此，对Linux中不同处理器架构可能采用的三种spinlock的实现方式的介绍就告一段落了，下文将开始介绍Linux中spinlock的具体使用方法。原创文章，转载请注明出处。编辑于 2020-04-13 00:12 操作系统 Linux 内核并行计算 Linux内核和虚拟化方向的技术分享. () and ros::spin() both block the main thread from exiting until ROS invokes a shutdown - via a Ctrl + C for example. They are written as the last line of code of the main thread of the program.
