- * This is the new flexible, extensible style NFSv2/v3 file handle.
+ * This is the new flexible, extensible style NFSv2/v3/v4 file handle.
* by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
*
* The file handle starts with a sequence of four-byte words.
*
* 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 auth_type field is deprecated and must be set to 0.
*
* The fsid_type identifies how the filesystem (or export point) is
* encoded.
* 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.
- *
+ * The values for this field are filesystem specific, exccept that
+ * filesystems must not use the values '0' or '0xff'. 'See enum fid_type'
+ * in include/linux/exportfs.h for currently registered values.
