[PATCH 00/22] virtqueue_add_sgs, virtqueue_add_outbuf, virtqueue_add_inbuf
Add virtqueue_add_sgs which is more general than virtqueue_add_buf,
which makes virtio-scsi and virtio-blk nicer, then add virtqueue_add_inbuf
and virtqueue_add_outbuf which handle the more general case, and finally
delete virtqueue_add_buf().
I'm hoping this will be the final post of the whole series, and it can
move from my pending-rebases tree into virtio-next.
Thanks!
Rusty.

[PATCH 0/5] vringh
This introduces vringh, which are generic accessors for virtio rings (host side).
There's a host-side implementation in vhost, but it assumes that the rings are
in userspace, and is tied to the vhost implementation. I have patches to adapt
it to use vringh, but I'm pushing this in the next merge window for Sjur, who has
CAIF patches which need it.
This also includes a test program in

[PATCH 1/6] virtio_host: host-side implementation of virtio rings.
Getting use of virtio rings correct is tricky, and a recent patch saw
an implementation of in-kernel rings (as separate from userspace).
This patch attempts to abstract the business of dealing with the
virtio ring layout from the access (userspace or direct); to do this,
we use function pointers, which gcc inlines correctly.
