Understanding the logical file system and the virtual file system.
了解逻辑文件系统和虚拟文件系统。
Previous versions of NFS did not have a method of allowing clients to build complex logical file system RPCs.
先前版本的NFS没有方法可以让客户机生成复杂逻辑的文件系统RPC。
The logical file system is also responsible for managing the kernel's open file table and the per process file descriptor information.
逻辑文件系统还负责管理内核的打开文件表和每个进程的文件描述符信息。
A virtual file system can be a physical file system, a network file system, or a logical file system (one that does not have a physical backing store, such as ramfs).
虚拟文件系统可以为物理文件系统、网络文件系统、或者逻辑文件系统(没有物理后备存储,如ramfs)。
The logical file system layer is the level of abstraction at which users can request the various file operations, such as read, write, stat, and so on.
逻辑文件系统层是一个抽象层,用户可以通过它请求各种文件操作,如读、写、获得相关信息,等等。
