Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
+ *
+ * The file handle is seens as a list of 4byte words.
+ * The first word contains a version number (1) and four 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 4byte 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 upto 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
+ *
+ * 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.
