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

20 unsigned char data[NFS_MAXFHSIZE];
24 * Returns a zero iff the size and data fields match.
25 * Checks only "size" bytes in the data field.

40 * This is really a general kernel constant, but since nothing like
41 * this is defined in the kernel headers, I have to do it here.
