 * This is the new flexible, extensible style NFSv2/v3 file handle.

 * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000

 *

 * The file handle starts with a sequence of four-byte words.

 * The first word contains a version number (1) and three descriptor bytes

 * that tell how the remaining 3 variable length fields should be handled.

 * These three bytes are auth_type, fsid_type and fileid_type.

 *

 * All four-byte values are in host-byte-order.

 *

 * The auth_type field specifies how the filehandle can be authenticated

 * This might allow a file to be confirmed to be in a writable part of a

 * filetree without checking the path from it up to the root.

 * Current values:

 *     0  - No authentication.  fb_auth is 0 bytes long

 * Possible future values:

 *     1  - 4 bytes taken from MD5 hash of the remainer of the file handle

 *          prefixed by a secret and with the important export flags.

 *

 * The fsid_type identifies how the filesystem (or export point) is

 *    encoded.

 *  Current values:

 *     0  - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number

 *        NOTE: we cannot use the kdev_t device id value, because kdev_t.h

 *              says we mustn't.  We must break it up and reassemble.

 *     1  - 4 byte user specified identifier

 *     2  - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED

 *     3  - 4 byte device id, encoded for user-space, 4 byte inode number

 *     4  - 4 byte inode number and 4 byte uuid

 *     5  - 8 byte uuid

 *     6  - 16 byte uuid

 *     7  - 8 byte inode number and 16 byte uuid

 *

 * The fileid_type identified how the file within the filesystem is encoded.

 * This is (will be) passed to, and set by, the underlying filesystem if it supports

 * filehandle operations.  The filesystem must not use the value '0' or '0xff' and may

 * only use the values 1 and 2 as defined below:

 *  Current values:

 *    0   - The root, or export point, of the filesystem.  fb_fileid is 0 bytes.

 *    1   - 32bit inode number, 32 bit generation number.

 *    2   - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.

 *
