This series implements virtio-scsi queue steering, which gives performance improvements of up to 50% (measured both with QEMU and tcm_vhost backends). This version rebased on Rusty's virtio ring rework patches, which has already gone into virtio-next today. We hope this can go into virtio-next together with the virtio ring rework pathes. V6: rework "redo allocation of target data" (James) fix comments (Venkatesh) rebase to virtio-next V5: improving the grammar of 1/5 (Paolo) move the dropping of sg_elems to 'virtio-scsi: use virtqueue_add_sgs for command buffers'. (Asias) V4: rebase on virtio ring rework patches (rusty's pending-rebases branch) V3 and be found http://marc.info/?l=linux-virtualization&m=136067440717154&w=2 It would probably be easier to get it in via Rusty's tree because of the prerequisites. James, can we get your Acked-by?
