Ext3 users - Mar 2003 - Updated 2.4 htree patches available for 2.4.21-pre5

There's a new set of ext2/3 patches for 2.4.21-pre5 available at:

  http://thunk.org/tytso/linux/extfs-2.4-update/extfs-update-2.4.21pre5-2

and in broken out form at:

  http://thunk.org/tytso/linux/extfs-2.4-update/broken-out-2.4.21pre5-2

New to this patch set include:

* A kludge to help htree work well with Linux's NFS implementation
* Allow the orlov allocator to be disabled via a mount option.
* Improvements to the inode and block allocators by Andrew Morton
* The bugfix for noatime on newly created inodes 
* An open by inode number extension (this was an old patch I developed a
	while ago, updated for the latest 2.4 kernels; nothing changes
	unless a filesystmem is mounted with the iopen or iopen_nopriv
	mount options; see Documentation/filesystems/ext2.txt for more 
	information)

Also included in this patchset (over stock 2.4.21rc5) are:

* dxdir/htree support for fast directory lookups 
* honor default mount options stored in the ext2/3 superblock.
* forward compatibility: dynamic resizing
* forward compatibility: larger inode size
* backport of the Orlov allocator from Linux 2.5

Where can I read up on it's mystical properties?

Is there anything special I have to do besides patching the kernel?
Special mount options for htree etc.

What are the *recommended* ext{2,3} mount options with this patch?

Best wishes

Norbert

Are there any specific tests that you suggest or would like to see run? 
I'm going to do some benchmarking using ext3+htree, reiserfs, and xfs
for the cache data store with squid, but would be happy to test other
things.

Thanks.

Is there any chance to get this patch working with the ea+acl patch from
bestbits (acl.bestbits.at)?

Best wishes

You mount read-only, run the above, then immediately reboot.

Question: It would be cool if the patch would manifest itself in the
dmesg output in any way, eg. I still only see:

EXT3 FS 2.4-0.9.19, 19 August 2002 on ide0(3,1), internal journal

instead of:
EXT3 FS 2.4-0.9.19+orlov/htree, 12 March 2003 on ide0(3,1), internal journal
