Subject: Ext2 Directory Index, updated

After some considerable time letting this patch 'age', here's an update
to 2.4.18:

http://people.nl.linux.org/~phillips/htree/htree-2.4.18

The diff to 2.4.17 was provided by Ted Ts'o, and bug hunting/fixing by
Chris Li (who has the rather interesting email address
<[email protected]>). Chris is working on the Ext3 port as well.

Bill Irwin is providing loving care and attention to the hash function, so I
feel it's in good hands.

Known Bug:

- highmem doesn't work (because the kmapping code is wrong)

To Do:

- Finalize hash function.
- Coalesce on delete. I have to do this sooner rather than later,
since hash bucket fragmentation leads quickly to reduced leaf
fullness.
- Stable telldir cookie for NFS
- Ext2 util updates (in progress, Ted Ts'o)
- Miscellaneous source cleanups

Because of the unfinalized hash function, this patch is still for testing
only.
