cregit-Linux how code gets into the kernel

Release 4.12 include/linux/nfs.h

 * NFS protocol definitions
 * This file contains constants mostly for Version 2 of the protocol,
 * but also has a couple of NFSv3 bits in (notably the error codes).
#ifndef _LINUX_NFS_H

#define _LINUX_NFS_H

#include <linux/sunrpc/msg_prot.h>
#include <linux/string.h>
#include <uapi/linux/nfs.h>

 * This is the kernel NFS client file handle representation

unsigned char		data[NFS_MAXFHSIZE];

 * Returns a zero iff the size and data fields match.
 * Checks only "size" bytes in the data field.
