[PATCH libnbd] generator: Define new Closure type
** INCOMPLETE **
This is the generator change as discussed on the list already.
The Python and OCaml bindings are not yet done.
It passes all [C only] tests and valgrind.
Note that nbd_add_close_callback is inconsistent with other closure
types because it passes the user_data parameter after the function.
(This is not caused by the current patch, it was already
inconsistent). We decided that

[libnbd PATCH v3 0/7] Avoid deadlock with in-flight commands
Since v2:
- rebase to Rich's new API calls
- more refactoring in patch 1 (retitled)
- new patches 3 and 4
- fix data corruption in patch 6 (was 4)
- more tweaks to the reproducer example (including using new API from 3)
Eric Blake (7):
lib: Refactor command_common() to do more common work
commands: Allow for a command queue
commands: Expose FIFO ordering of server completions

[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.
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
