LT		 1/*
2 * linux/fs/nfs/proc.c
3 *
4 * Copyright (C) 1992, 1993, 1994 Rick Sladkey
5 *
6 * OS-independent nfs remote procedure call functions
7 *
8 * Tuned by Alan Cox <A.Cox@swansea.ac.uk> for >3K buffers
9 * so at last we can have decent(ish) throughput off a
10 * Sun server.
11 *
12 * Coding optimized and cleaned up by Florian La Roche.
13 * Note: Error returns are optimized for NFS_OK, which isn't translated via
14 * nfs_stat_to_errno(), but happens to be already the right return code.
15 *
16 * Also, the code currently doesn't check the size of the packet, when
17 * it decodes the packet.
18 *
19 * Feel free to fix it and mail me the diffs if it worries you.
20 *
21 * Completely rewritten to support the new RPC call interface;
22 * rewrote and moved the entire XDR stuff to xdr.c
23 * --Olaf Kirch June 1996
24 *
25 * The code below initializes all auto variables explicitly, otherwise
26 * it will fail to work as a module (gcc generates a memset call for an
27 * incomplete struct).
