The vfs layer provides an administrative interface into the file system to support commands like mount and umount in a file-system-independent manner. The interface achieves independence by means of a virtual file system (vfs) object. The vfs object represents an encapsulation of a file system's state and a set of methods for each of the file system administrative interfaces. Each file system type provides its own implementation of the object. Figure 13.3 illustrates the vfs object.
