[CFT] ZFS v15 patch (version 3)

Sat Jul 24 03:19:40 UTC 2010

Forwarding to the list.

I put the patch on a Sun blade 100 with 256 megs of ram
and no issues so far.  (sparc64 architecture)

This
 machine only has 256 megs of memory, but i made two 100 megabyte memory
 disks, 
mirrored them, wrote some stuff, offlined each one 
individually, and it all worked okay.
