Step two: data is copied from the kernel buffer into the user buffer, and the read system call returns. The return from the call caused a context switch from kernel back to user mode.
步骤二：数据从内核空间缓冲区复制到用户空间缓冲区，之后系统调用read返回，这导致了从内核空间向用户空间的上下文切换。
To better understand model-centric development concepts, take a step back from the code and analyze the behaviour of your system.
为了更好地理解以模型为中心的开发的概念，需要退一步回到源代码并且分析系统的行为。
This definition sounds like that of a transactional mechanism in a database management system, in which a step can be rolled back if it is not performed correctly.
该定义听起来像是数据库管理系统中的一个事务性机理，如果它没有正常运行的话该步骤可以返回。
He pledged that if taxpayers ever had to step in again to rescue the system, they would get every cent back, a nonsensical promise.
他还承诺，如果再次出现纳税者拿钱拯救体系的情况，他们将得到回报。这基本上是个荒诞的许诺。
If the current checkpoint was invalid, the file system need only step back to the last good checkpoint for a valid file system.
如果当前检查点失效，文件系统只需回滚到上一个有效的检查点，重新获得有效的文件系统。
