[PATCH 1/3] Virtio draft IV
In response to Avi's excellent analysis, I've updated virtio as promised
(apologies for the delay, travel got in the way).
===
This attempts to implement a "virtual I/O" layer which should allow
common drivers to be efficiently used across most virtual I/O
mechanisms. It will no-doubt need further enhancement.
The details of probing the device are left to hypervisor-specific

[libnbd PATCH 0/6] new APIs: aio_in_flight, aio_FOO_notify
I still need to wire in the use of *_notify functions into nbdkit to
prove whether it makes the code any faster or easier to maintain, but
at least the added example shows one good use case for the new API.
Eric Blake (6):
api: Add nbd_aio_in_flight
generator: Allow DEAD state actions to run
generator: Allow Int64 in callbacks
states: Prepare for aio notify callback
api: Add new
