Jeff's SUJ work is for UFS I believe, and is heavily integrated into
softupdates. It is a partial solution to UFS's fsck issue which, with
some more work, could potentially become a full solution.
We basically do not use UFS any more except for /boot or on very small
drives. HAMMER is used for anything bigger than 50G or so.
I stopped bringing in UFS stuff several years ago (prior to the UFS
snapshots and background fsck) and I really don't want to bring in
those pieces. What we have now is nice and stable and I don't want
to mess with it.
