The following patches are a second (actually third if you count when I tried to fixup all their duplicated code but broke a lot of features the first time) try at converting sg and st to not use scsi_requests and always use scatterlists. It is not the grand cleanups I had hoped to do. It does allow us to finish converting scsi-ml and LLDs without breaking anything though. It is also a nice bit of cleanup for sg. I do hope to still move the the ULDs to use the block layer blk_rq_map_user* functions for DIO and copy_to/from_user cases so we can kill a lot of their code. And we should be able to consolidate their buffer allocation code soon. If these patches are ok, we just have to convert gdth, osst and cpqfc. - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
