This permanent data is just file data.

这种永久数据就是文件数据。

As mentioned earlier, an unmodified permanent storage page can just be released without being written to the file system, since the file system contains a pristine copy of the data.

如前所述，可以直接释放没有经过修改的永久存储分页，无需将其写入到文件系统中，因为文件系统包含该数据的原始副本。

As a program does reads and writes to the file, the AIX kernel caches the file's data in memory as non-computational permanent storage pages.

随着程序对该文件进行读写操作，AIX内核将该文件的数据作为非计算性的永久存储分页在内存中进行缓存。
