[PATCHv2 00/14] virtio and vhost-net performance enhancements
OK, here is the large patchset that implements the virtio spec update
that I sent earlier (the spec itself needs a minor update, will send
that out too next week, but I think we are on the same page here
already). It supercedes the PUBLISH_USED_IDX patches I sent
out earlier.
What will follow will be a patchset that actually includes 4 sets of
patches. I note below their status. Please consider

[PATCH 00/18] virtio and vhost-net performance enhancements
OK, here's a large patchset that implements the virtio spec update that I
sent earlier. It supercedes the PUBLISH_USED_IDX patches
I sent out earlier.
I know it's a lot to ask but please test, and please consider for 2.6.40 :)
I see nice performance improvements: one run showed going from 12
to 18 Gbit/s host to guest with netperf, but I did not spend a lot
of time testing performance,
