Well .. so far everything runs smoothly on my FreeBSD/amd64
8.0-CURRENT. I upgraded a simple one-disk ZPOOL and all ZFS
filesystems on it without problems.
The only thing that caught my eye were the  console warnings like the
ones below:

WARNING pid 1413 (zpool): ioctl sign-extension ioctl ffffffffcc285a09
WARNING pid 1473 (zfs): ioctl sign-extension ioctl ffffffffcc285a12
WARNING pid 1473 (zfs): ioctl sign-extension ioctl ffffffffcc285a15

I only saw the zpool one once the zfs ones are mostly the
ffffffffcc285a12. I am not exactly sure what those warnings are trying
to tell me but thought i should at least mention them here.
