Okay, that part I misread from the message, but that leaves the question of
"does it work?" Iirc, Jeff Merkey tested variable sized ios with nwfs, but
found that triggered bugs in the low level drivers, some of which assume that
all buffer heads within a request have the same block size. Given that
concern, I really don't think this is a safe 2.4 patch.
