Select the last Return from the call path to see the result as shown in Figure 51.
从调用路径中选择最后一个Return,以创建结果,如图51中所示。
Upon return from the system call, syscall_exit is eventually reached, and a call to resume_userspace transitions back to user-space.
从系统调用中返回后,最终执行syscall_exit,并调用resume_userspace返回用户空间。
This is an important difference to note since you are probably used to the case where a return from a method call implies that its work has finished completely.
这是一个要非常注意的不同点,因为您可能已经习惯了这样的一种情况——一个方法调用返回后就意味着该方法正确执行完毕了。
