Currently, vhost-net is the only consumer of vhost infrastructure. So vhost infrastructure and vhost-net driver are in a single module. Separating this as a vhost.ko module and a vhost-net.ko module makes it is easier to share code with other vhost drivers, e.g. vhost-blk.ko, tcm-vhost.ko.

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.
