- * UNIX		An implementation of the AF_UNIX network domain for the
- *		LINUX operating system.  UNIX is implemented using the
- *		BSD Socket interface as the means of communication with
- *		the user level.
- *
- *		This file describes some things of the UNIX protocol family
- *		module.  It is mainly used for the "proc" sub-module now,
- *		but it may be useful for cleaning up the UNIX module as a
- *		whole later.
- *
- * Version:	@(#)unix.h	1.0.3	05/25/93
- *
- * Authors:	Orest Zborowski, <obz@Kodak.COM>
- *		Ross Biro, <bir7@leland.Stanford.Edu>
- *		Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
- *
- * Fixes:
- *		Dmitry Gorodchanin	-	proc locking
- *
- *		This program is free software; you can redistribute it and/or
- *		modify it under the terms of the GNU General Public License
