Yeah, v8 is working for me.

I'm seeing it a bit slower for some blocksizes, but faster (or perhaps 
about the same within repeat measurement error) for others:

blocksize k |  patched iops | orig iops
------------+---------------+-----------
4           | 12265         | 11930
128         |  5800         |  7100
1024        |  1193         |  1196

Mark
