I had a drive in a raidz2 pool fail, and wasn't able to replace it until 
rebuilding the kernel (7.0beta3) with the above patch.  I'm just 
mentioning this as a worksforme kind of thing.

I'm rebuilding today with RELENG_7_0 and saw that the patch still 
applied cleanly, so I'm assuming it's still necessary.  I hope it or 
something similar gets merged in.  Or at least maybe the ZFS wiki could 
have a list of recommended patches?
