I think it would be better if the ctrl will hold a virt_boundary provided by the fabric driver? Then we would always blk_queue_virt_boundary but with capable devices the fabric driver can set it to 0. This will also allow for dword aligned sgls to fit in pretty easily. -- 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
