- * Root Plug sample LSM module
- *
- * Originally written for a Linux Journal.
- *
- * Copyright (C) 2002 Greg Kroah-Hartman <greg@kroah.com>
- *
- * Prevents any programs running with egid == 0 if a specific USB device
- * is not present in the system.  Yes, it can be gotten around, but is a
- * nice starting point for people to play with, and learn the LSM
- * interface.
- *
- * If you want to turn this into something with a semblance of security,
- * you need to hook the task_* functions also.
- *
- * See http://www.linuxjournal.com/article.php?sid=6279 for more information
- * about this code.
