[PATCH nbdkit] tests: Convert some tests to use nbdsh instead of qemu-io.
Very much a work in progress as there are still many tests using
qemu-io which are candidates for conversion.
You'll notice at the end of test-full.sh that the new test has some
duplicated code which looks as if it ought to be refactored into a
Python function. When I tried to do that, I got loads of strange
Python problems which may indicate bugs in nbdsh itself or problems
with my

[PATCH libnbd] api: Get rid of nbd_connection.
This isn't quite finished because not all of the tests or examples
have been updated, but it demonstrates an idea: Should we forget about
the concept of having multiple connections managed under a single
handle?
In this patch there is a single ‘struct nbd_handle *’ which manages a
single state machine and connection (and therefore no nbd_connection).
To connect to a multi-conn server you must

[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.

[libnbd PATCH v2 00/13] Adding nbd_set_opt_mode to improve nbdinfo
Well, I'm not quite done (I still want to get nbdinfo to work on a
single nbd connection for all cases when reading the heads of the
file is not required), but I'm happy with patches 1-11, and 12-13
show where I'm headed for getting NBD_OPT_INFO to work. Posting
now to see if some of the earlier patches are ready to commit while
I continue working on the latter half.
