[libnbd PATCH 0/3] opt_list_meta_context
I'm posting this now, as I'm at the end of a workday and I got things
working for manual experimentation.
Still to do:
- write interop tests for qemu-nbd and nbdkit (including my proposed
patch addition of qemu-nbd -A to show qemu:allocation-depth)
- figure out if we can make 'nbdinfo --map' use the new API to
automatically select all contexts advertised by the server

[PATCH libnbd 0/5] info: --map: Coalesce adjacent extents of the same type.
This adds coalescing of adjacent extents of the same type, as
mentioned by Eric Blake in the commit message here:
https://github.com/libguestfs/libnbd/commit/46072f6611f80245846a445766da071e457b00cd
The patch series is rather long because it detours through adding the
<vector.h> library from nbdkit into libnbd and replacing ad hoc uses
of realloc, char ** etc in various places.
Rich.

[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

states: Prepare for aio notify callback
