To add another report, I've been running your patch on one machine
since late October/early November, and just installed another one
with it a week ago. I haven't gotten any panics on either. I just
did a make clean && make buildworld && make buildkernel && make
clean (and ran the final make clean 9 times for good measure) on
the second machine to try to reproduce the reported panic, but it
worked fine. Both machines are running FreeBSD 8.0-STABLE/amd64
with ZFS from -CURRENT as of Dec 4, plus your patch.

This patch is essentially mandatory for me to be able to run ZFS,
since otherwise I can't backup my ZFS pools...
