Description

Very old dataset upgrade path, fails with:

VERIFY3 " "failed ("
"0xffffff824e87a100" " " "==" " " "0xffffff824e87b980" ")\n"@dmu_objset.c:579

Can be triggered with:

mkfile 256m filepool.bin
zpool create -o version=1 -O version=1 fp `pwd`/filepool.bin
zfs upgrade -V 2 fp
zfs upgrade -V 3 fp
zpool upgrade -V 9 fp
zfs upgrade -V 3 fp
zfs upgrade -V 4 fp
zpool upgrade -V 15 fp
zfs upgrade -V 4 fp

triggers on IllumOS, ZOL, FreeBSD and OS X.

Removing the VERIFY does technically stop it from causing a panic, and the
pool/dataset is upgraded, but, well, I don't know if there are side-effects
from doing that.
