His name is Dominic Giampaolo and his page is <http://www.nobius.org/~dbg/>.

It seems that you understood me incorrectly here. What I said was that it
seems that HFS+ with journalling enabled is similar to ext3 in the sense
that they both have "hidden files" (not that hidden, of course) where they
seem to put their transactions.
Mounting a journalled HFS+ FS in Linux and deleting the journal files seems
to make MacOS X think that the filesystem is a regular HFS+ FS.

I didn't say in any moment that they share any code, because:
* I don't know if they share any code;
* I guess that there would be legal problems mixing ext3 code with code in
Darwin, due to their licences.
Hope this clears the confusion, Rogério.
