Hi Sagi, (Very) nice cleanup -- so what's the actual deal here? is that as long as we plant a slave alloc callback into out scsi host template which further invokes a blk_queue_virt_boundary(sdev->request_queue, ~MASK_4K) call, we're 100% safe/sure what all SGs we get meet the alignment criteria? Since this is such a critical aspect in our design, I think it would be good to copy on this commit Martin or Jens. Also change the patch title to have IB/iser: which complies with the way we prefix iser commits. Or. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
