The ufs fixes are looking good, much better than what we started with.
After applying the 8 ufs patches:

Copying files to FreeBSD 11.0 (ufs2) and NetBSD 7.1 (ufs2) looks
pretty good.
I can copy a large >2GB file, create a directory and then run and
fsck without errors with a FreeBSD disk and a NetBSD disk.
But...
1) Creating an OpenBSD 6.1 (44bsd) disk and then on Linux copying a
large > 2GB file and creating a directory, there are errors on OpenBSD
with the fsck:
OpenBSD (44bsd):
#fsck sd0e
** /dev/rsd0e
** File system is already clean
** Last Mounted on /diske
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
FREE BLK COUNT(S) WRONG IN SUPERBLK
SALVAGE? [Fyn?]
3 files, 1272410 used, 6983197 free (13 frags, 872898 blocks, 0.0% fragmentation)
***** FILE SYSTEM WAS MODIFIED *****
And also after removing the files on Linux, there were errors in
the fsck on OpenBSD:
#fsck sd0e
** /dev/rsd0e
** File system is already clean
** Last Mounted on /diske
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts

SALVAGE? [Fyn?]
1 files, 1 used, 8255606 free (14 frags, 1031949 blocks, 0.0% fragmentation)
***** FILE SYSTEM WAS MODIFIED *****
2) The available block counts on a newly created FreeBSD 11.0
ufs2 filesystem (13079640) differ from Linux 4.12-rc4 (13079656):
Freebsd (ufs2):
#df /diske
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ada0s3e 14217008 8 13079640 0% /diske
Linux:
#df /fbsd23
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda23 14217008 8 13079656 1% /fbsd23
3) The available block counts on a newly created NetBSD 7.1
ufs2 filesystem (9518316) differ from Linux 4.12-rc4 (9518314):
NetBSD (ufs2):
#df /nbsdf
