[PATCH V5 0/5] virtio-scsi multiqueue

From: Wanlong Gao
Date: Tue Mar 19 2013 - 05:59:32 EST

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.
We hope this can go into virtio-next together with the virtio ring
rework pathes.

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?

Paolo Bonzini (4):
virtio-scsi: redo allocation of target data
virtio-scsi: pass struct virtio_scsi to virtqueue completion function
virtio-scsi: push vq lock/unlock into virtscsi_vq_done
virtio-scsi: introduce multiqueue support

Wanlong Gao (1):
virtio-scsi: reset virtqueue affinity when doing cpu hotplug
