2 * INET An implementation of the TCP/IP protocol suite for the LINUX
3 * operating system. INET is implemented using the BSD Socket
4 * interface as the means of communication with the user level.
6 * This file implements the various access functions for the
7 * PROC file system. It is mainly used for debugging and

14 * Fred Baumgarten, <dc6iq@insu1.etec.uni-karlsruhe.de>
15 * Erik Schoenfelder, <schoenfr@ibr.cs.tu-bs.de>
18 * Alan Cox : UDP sockets show the rxqueue/txqueue
19 * using hint flag for the netinfo.
20 * Pauline Middelink : identd support
21 * Alan Cox : Make /proc safer.
22 * Erik Schoenfelder : /proc/net/snmp
23 * Alan Cox : Handle dead sockets properly.
24 * Gerhard Koerting : Show both timers
25 * Alan Cox : Allow inode to be NULL (kernel socket)
26 * Andi Kleen : Add support for open_requests and
27 * split functions for more readibility.
28 * Andi Kleen : Add support for /proc/net/netstat
