- * 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.
- *
- *		The functions in this file provide an interface between
- *		the PROC file system and the "unix" family of networking
- *		protocols. It is mainly used for debugging and statistics.
- *
- * Version:	@(#)proc.c	1.0.4	05/23/93
- *
- * Authors:	Ross Biro, <bir7@leland.Stanford.Edu>
- *		Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
- *		Gerald J. Heim, <heim@peanuts.informatik.uni-tuebingen.de>
- *		Fred Baumgarten, <dc6iq@insu1.etec.uni-kalrsruhe.de>
- *
- * Fixes:
- *		Dmitry Gorodchanin	:	/proc locking fix
- *		Mathijs Maassen		:	unbound /proc fix.
- *		Alan Cox		:	Fix sock=NULL race
