[PATCH RESEND 0/5] Add vhost-blk support
Hi folks,
[I am resending to fix the broken thread in the previous one.]
This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk
device accelerator. Compared to userspace virtio-blk implementation, vhost-blk
gives about 5% to 15% performance improvement.
Asias He (5):
aio: Export symbols and struct kiocb_batch for in kernel aio usage

[RFC] [ver3 PATCH 0/6] Implement multiqueue virtio-net
This patch series resurrects the earlier multiple TX/RX queues
functionality for virtio_net, and addresses the issues pointed
out. It also includes an API to share irq's, f.e. amongst the
TX vqs.
I plan to run TCP/UDP STREAM and RR tests for local->host and
local->remote, and send the results in the next couple of days.
