Two quick questions:

- Do you think this fix would improve or fix the panic below?
   (transcribed by hand since it did not dump and I only have a
    screenshot)
- Are the many misc ZFS fixes that went into 9.0 and 8.0 going to
   be MFC'ed to 7-stable sometime, including the one above? I have
   lucked out pretty well so far since May.

Thanks.
