Mike Miller (OS Dev) 03bbfee58d cciss: add SG_IO ioctl to cciss
For all of you that think cciss should be a scsi driver here is the patch that
you have been waiting for all these years. This patch actually adds the SG_IO
ioctl to cciss. The primary purpose is for clustering and high-availibilty.
But now anyone can exploit this ioctl in any manner they wish.

Note, SCSI_IOCTL_SEND_COMMAND doesn't work with this patch due to rq->errors
being set incorrectly.  Subsequent patch fixes that.
