Subject: [PATCH v3 0/5] virtio-scsi multiqueue

This series implements virtio-scsi queue steering, which gives
performance improvements of up to 50% (measured both with QEMU and
tcm_vhost backends).  The patches build on top of the new virtio APIs
at http://permalink.gmane.org/gmane.linux.kernel.virtualization/18431;
the new API simplifies the locking of the virtio-scsi driver nicely,
thus it makes sense to require them as a prerequisite.

Changes from the previous post, which can be found at
http://permalink.gmane.org/gmane.linux.kernel.virtualization/17869:

- patches 1 and 2 ("virtio: add functions for piecewise addition of
  buffers", "virtio-scsi: use functions for piecewise composition of
  buffers") split into their own series

- new cleanup patch "virtio-scsi: push vq lock/unlock into virtscsi_vq_done"

- reorganized code to move ACCESS_ONCE in a clearer place

- included Wanlong Gao's CPU hotplug patches

Ok for 3.9?  It would probably be easier to get it in via Rusty's tree
because of the prerequisites.  James, can I get your Acked-by?
