Subject: 2.6.26-rc7-mmotd-0626 ext3-validate-directory-entry-data-before-use.patch

I'm seeing some ext3 errors, and I'm suspecting the patch
ext3-validate-directory-entry-data-before-use.patch is causing them
(since it seems to be the only thing in rc7-mmotd at the moment that
touches make_indexed_dir, and -rc5-mm3 works OK).

I believe I have a reasonably good replicator for the error on dm-7, that's my /usr/share
and trying to 'rpm -Fvh' one specific RPM has caused it twice (in two tries).

The file systems appear to be OK (or at least the fsck.ext3 in Fedora's
e2fsprogs-1.41-0.WIP.0617.1.fc10.x86_64 says both file systems are in fact OK).

Any comments/suggestions?  Any testing/debugging you'd like, or should I just revert it
and move on?
