40+ * This is the new flexible, extensible style NFSv2/v3 file handle.
41+ * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
42+ *
43+ * The file handle starts with a sequence of four-byte words.
44+ * The first word contains a version number (1) and three descriptor bytes
45+ * that tell how the remaining 3 variable length fields should be handled.
46+ * These three bytes are auth_type, fsid_type and fileid_type.
47+ *
48+ * All four-byte values are in host-byte-order.
49+ *
50+ * The auth_type field specifies how the filehandle can be authenticated
51+ * This might allow a file to be confirmed to be in a writable part of a
52+ * filetree without checking the path from it up to the root.
53+ * Current values:
54+ * 0 - No authentication. fb_auth is 0 bytes long
55+ * Possible future values:
56+ * 1 - 4 bytes taken from MD5 hash of the remainer of the file handle
57+ * prefixed by a secret and with the important export flags.
58+ *
59+ * The fsid_type identifies how the filesystem (or export point) is
60+ * encoded.
61+ * Current values:
62+ * 0 - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
63+ * NOTE: we cannot use the kdev_t device id value, because kdev_t.h
64+ * says we mustn't. We must break it up and reassemble.
65+ * 1 - 4 byte user specified identifier
66+ * 2 - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
67+ * 3 - 4 byte device id, encoded for user-space, 4 byte inode number
68+ * 4 - 4 byte inode number and 4 byte uuid
69+ * 5 - 8 byte uuid
70+ * 6 - 16 byte uuid
71+ * 7 - 8 byte inode number and 16 byte uuid
72+ *
73+ * The fileid_type identified how the file within the filesystem is encoded.
74+ * This is (will be) passed to, and set by, the underlying filesystem if it supports
75+ * filehandle operations. The filesystem must not use the value '0' or '0xff' and may
76+ * only use the values 1 and 2 as defined below:
77+ * Current values:
78+ * 0 - The root, or export point, of the filesystem. fb_fileid is 0 bytes.
79+ * 1 - 32bit inode number, 32 bit generation number.
80+ * 2 - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.
