/**
* @defgroup DFS Device Virtual File System
*
* @brief DFS is a virtual file system in RT-Thread RTOS.
*
* The DFS (Device Virtual File System) is a vfs file system of RT-Thread RTOS,
* which is focused on embedded device. VFS is an abstraction layer on top of a
* more concrete file system. The purpose of a VFS is to allow client applications
* to access different types of concrete file systems in a uniform way.
*
* @image html dfs.png "Figure 4: Device Virtual File System Architecture"
*
* The DFS specifies an interface between the kernel and a concrete file system.
* Therefore, it is easy to add support for new file system types to the kernel
* simply by fulfilling the interface.
