OK, here's the cumulative diff so far - easy-to-backport parts only; that'll
be split into 6 commits (plus whatever else gets added). It really needs
beating...
On OpenBSD 6.1 (UFS-1) the "df ." test did not look so good before
applying the cumulative diff:
Linux 4.12-rc4:
#mount -t ufs -o rw,ufstype=44bsd /dev/sda19 /diske
#df .
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda19 16511214 2 15685652 1% /diske
#mkdir a
#rmdir a
#df .
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda19 16511214 18 15685636 1% /diske
OpenBSD 6.1:
#fsck -f sd0e
** /dev/rsd0e (NO WRITE)
** File system is already clean
** Last Mounted on
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups

But after applying the accumulative diff patch set it looks great:
Linux 4.12-rc4-viro-1:
#mount -t ufs -o rw,ufstype=44bsd /dev/sda19 /diske
#cd /diske
#df .
