This article explores how this is done and investigates the major structures of the Linux file system layer.
本文讲解这个机制的实现方法并介绍Linux文件系统层的主要结构。
Now that you've seen file system construction in action, I'll get back to the architecture of the Linux file system layer.
既然已经看到了文件系统的构造方法，现在就看看Linux 文件系统层的体系结构。
To illustrate the capabilities of the Linux file system layer (and the use of mount), create a file system in a file within the current file system.
为了说明Linux文件系统层的功能（以及挂装的方法），我们在当前文件系统的一个文件中创建一个文件系统。
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。
Below the file system layer is the buffer cache, which provides a common set of functions to the file system layer (independent of any particular file system).
文件系统层之下是缓冲区缓存，它为文件系统层提供了一个通用函数集(与具体文件系统无关)。
Currently the main storage system technology is SAN Virtualization and its implementation is in the file system layer.
SAN的虚拟化是存储系统的发展趋势，它在文件系统层实现。
From a storage perspective, Ceph object storage devices perform the mapping of objects to blocks (a task traditionally done at the file system layer in the client).
从存储角度来看，Ceph对象存储设备执行从对象到块的映射(在客户端的文件系统层中常常执行的任务)。
