Well, I _do_ have a more up-to-date ext3 online resize patch for 2.2
(a completely different implementation than the above), but I have never
finished the support for it in the user tools (it has a different on-disk
format for the reserved inode).  I have never released this code publicly
(to a few people privately, and at one point some people had said they
would finish the support in the user tools, which never happened).

The other problem was that this was built on a 2.2 ext3 codebase that
also had a lot of other patches in it (LFS and other changes) so it was
also too much work to just release the online resizing part of the patch.

"One day" I will port this to 2.4, but if you have some interest in
doing so, it should be a relatively straight forward port, and I can
send you the patch.  As always, if enough people bug me about it, I'm
more likely to work on it when I get a chance.  As it is, I never hear
whether people are using ext2online (not even bug reports, except the
occasional question about a patch for a newer kernel), so there doesn't
"appear" to be a demand for this, to me at least.

Cheers, Andreas
