- *  gjh 3/'93 heim@peanuts.informatik.uni-tuebingen.de (Gerald J. Heim)
- *            most of this file is stolen from base.c
- *            it works, but you shouldn't use it as a guideline
- *            for new proc-fs entries. once i'll make it better.
- * fvk 3/'93  waltje@uwalt.nl.mugnet.org (Fred N. van Kempen)
- *	      cleaned up the whole thing, moved "net" specific code to
- *	      the NET kernel layer (where it belonged in the first place).
- * Michael K. Johnson (johnsonm@stolaf.edu) 3/93
- *            Added support from my previous inet.c.  Cleaned things up
- *            quite a bit, modularized the code.
- * fvk 4/'93  waltje@uwalt.nl.mugnet.org (Fred N. van Kempen)
- *	      Renamed "route_get_info()" to "rt_get_info()" for consistency.
- * Alan Cox (gw4pts@gw4pts.ampr.org) 4/94
- *	      Dusted off the code and added IPX. Fixed the 4K limit.
- * Erik Schoenfelder (schoenfr@ibr.cs.tu-bs.de)
- *	      /proc/net/snmp.
- * Alan Cox (gw4pts@gw4pts.ampr.org) 1/95
- *	      Added AppleTalk slots
- *
- *  proc net directory handling functions
