[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.

This series implements virtio-scsi queue steering, which gives

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.

[PATCH 0/6] virtio_add_buf replacement.
OK, so I've spent a few days benchmarking. Turns out 80% of
virtio_add_buf cases are uni-directional (including the
always-performance-sensitive networking code), and that gets no
performance penalty (though tests with real networking would be
appreciated!).
I'm not reposting all the "convert driver to virtio_add_outbuf()"
patches: just the scsi one which I didn't have
