/* * linux/fs/nfs/proc.c * * Copyright (C) 1992, 1993, 1994 Rick Sladkey * * OS-independent nfs remote procedure call functions * * Tuned by Alan Cox <A.Cox@swansea.ac.uk> for >3K buffers * so at last we can have decent(ish) throughput off a * Sun server. * * Coding optimized and cleaned up by Florian La Roche. * Note: Error returns are optimized for NFS_OK, which isn't translated via * nfs_stat_to_errno(), but happens to be already the right return code. * * Also, the code currently doesn't check the size of the packet, when * it decodes the packet. * * Feel free to fix it and mail me the diffs if it worries you. * * Completely rewritten to support the new RPC call interface; * rewrote and moved the entire XDR stuff to xdr.c * --Olaf Kirch June 1996 * * The code below initializes all auto variables explicitly, otherwise * it will fail to work as a module (gcc generates a memset call for an * incomplete struct). */ #include <linux/types.h> #include <linux/param.h> #include <linux/slab.h> #include <linux/time.h> #include <linux/mm.h> #include <linux/utsname.h> #include <linux/errno.h> #include <linux/string.h> #include <linux/in.h> #include <linux/pagemap.h> #include <linux/sunrpc/clnt.h> #include <linux/nfs.h> #include <linux/nfs2.h> #include <linux/nfs_fs.h> #include <linux/nfs_page.h> #include <linux/lockd/bind.h> #include <linux/smp_lock.h> #include "internal.h" #define NFSDBG_FACILITY NFSDBG_PROC /* * Bare-bones access to getattr: this is for nfs_read_super. */ static int nfs_proc_get_root(struct nfs_server *server, struct nfs_fh *fhandle, struct nfs_fsinfo *info) { struct nfs_fattr *fattr = info->fattr;
