[PATCH V2 RFC 1/9] virtio_ring: change host notification API
Rusty,
here is just patch 1 (using bool as return value in notify API).
Thanks.
Heinz Graalfs (9):

[PATCH V2 RFC 0/9] virtio: fix hang(loop) after hot-unplug vlan
Hi,
this patch-set solves a hang situation when a vlan network device is
hot-unplugged from a KVM guest.
On System z there exists no handshake mechanism between host and guest
when a device is hot-unplugged. The device is removed and no further I/O
is possible.
The guest is notified about the hard removal with a CRW machine check.
As per architecture, the host must repond to any I/O operation

[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.
