That means doing operation on cd rom, keyboard,mouse ?" VFS is a upper layer of all the filesystem and all the module register its file operation into this layer. So Whenever you doing operation on any file, VFS layer receive the request and redirect into corresponding registered module operation. I don't think we can do the operation without vfs. Please correct me if i am wrong.
