Beware, ZFS on head!

Depending on how you build it, you may either get a kernel compile failure (if 
you build zfs into the core kernel with "options ZFS"), or possibly even an 
invalid zfs.ko with an undefined symbol that can't be used at reboot time.  Be 
exceptionally careful.

I suggest, before rebooting, do a 
# nm /boot/kernel/zfs.ko | grep atomic_dec

If you see:
  U atomic_dec_64_nv
.. you will have a sub-optimal reboot experience and you may want to save your 
kernel.old.

(no output => you're fine => carry on!)
