process permanent file的意思|示意

If a file contains executable text for a process, the system treats the file as computational and marks all of the permanent storage pages in the file as computational.

如果一个文件包含某个进程的可执行文本，那么系统会将该文件视为计算性的，并且将该文件中的所有永久存储分页都标记为计算性的。

When a process page faults on a file (meaning the process references a part of the file that is not currently cached in memory in a permanent storage page), the process generates a page fault.

当对某个文件出现进程缺页(意味着该进程引用了文件的部分内容，而这部分内容当前没有缓存在永久存储分页的内存中)的时候，该进程将产生一个缺页。
