Hi!

I have made a small statistics for sd.c about use_sg (on SunESP).
In about 60% it was 1. That makes me wonder why this is not special cased,
ie. why requeue_sd_request does not set use_sg to 0 in that case, doesn't
try to allocate struct scatterlist etc. It could make some things faster, I
mean.

Cheers,
    Jakub
