Anyone have a SUJ patch set for 8.x ?

This backports SUJ from head to stable/8 (at r208799), by cherry-picking
the following revisions:

I have tested:
- Applying this diff to stable/8 at r208799 (any other rev is NOT
guaranteed to work, but there is a good chance, if not too far off)
- Doing a full buildworld, buildkernel, installkernel, reboot,
installworld and mergemaster.
- Enabling SUJ on a big filesystem with "tunefs -j enable".
- Randomly resetting the box during a large copy operation on that
filesystem, seeing the journal is replayed at boot time, and the
filesystem recovered.
That said, there is NO WARRANTY that this patch works properly. It
could hose all your filesystems, and/or cause irreversible damage to
your system. Most likely, even. You have been warned. :)
Also, please do NOT bother Jeff Roberson about this, as he is probably
busy enough supporting SUJ in head. :) Instead, direct any problem
reports to me first, or to the freebsd-stable mailing list, if you
prefer.

I wasn't sure what SUJ was, so I looked it up and it sounds like a great
feature to come to FreeBSD. I also found this email from Jeff that may be a
good resource as well.
