vfs_extfs example

This example demonstrates how to mount file systems of a block device.

The FileVfs program implements the server portion of the virtual file system, thereby providing the interface used for interaction with file systems and block devices. The Client program sends requests to the FileVfs program via IPC to mount file systems (ext2, ext3, ext4) to the specified directories and perform basic operations with files (create, write, read, and delete) to verify that the file systems are mounted correctly.
