[PATCH 0/6] Implement OClosure.
Patches 1-4 are basically uncontroversial, straightforward refactoring
and IMHO we should just push them. Possibly 1-3 should be squashed
together, but I posted them separately so they are easier to review.
Patches 5 and 6 together implement OClosure. Patch 5 adds the feature
and is simple to understand.
Patch 6 changes the Closure completion callbacks into OClosure, but
because it doesn't

[PATCH libnbd 0/2] generator: Preparatory changes to the generator.
These are some simplifications to the generator. They don't probably
make much sense on their own, but they are preparatory to better
handling of enums, and or'd lists of flags.

[PATCH libnbd v3] Add Go language bindings (golang) (RHBZ#1814538).
This feature is roughly finished now, although it needs a few more
tests and some examples.
It's pretty much up to par with all the other bindings, but it lacks a
completely safe AIO buffer. It won't stop you from freeing the buffer
too early) because golang's GC inexplicably lacks a way to declare a
root from C. I can probably do it with a global variable and ref

[PATCH libnbd v4] Add Go language bindings (golang) (RHBZ#1814538).
Now runs a complete set of tests, notably including the AIO test.
File descriptors are passed in and out as plain ints (instead of
*os.File) for a couple of reasons: (1) We have to pass the plain int
to syscall.Select. (2) Turning an fd into an os.File causes golang to
set the blocking flag which is deeply unhelpful.

[PATCH libnbd] Add bindings for Rust language
Still not working, but I took the latest patch and:
- rebased it against libnbd 1.0
- fixed it so it handles new args and cbargs
The generator now runs without warnings.
This patch doesn't handle optargs at all. In C these are converted to
non-optional parameter. Rust doesn't (AFAIK) have optional or
labelled arguments unfortunately.

[PATCH libnbd 0/5] WIP: python: Add test for doing asynch copy.
This doesn't yet work. However it does make me more convinced than
ever that we really need to sort out persistent buffer lifetimes in
the library (similar to what we did for closures).

[PATCH libnbd 0/4] Add free function to callbacks.
Patches 1 & 2 are rather complex, but the end result is that we pass

[PATCH libnbd 0/9] Add Enum and Flags types.
This largish series adds several new features to the generator.
Enum maps to enumerated types (like enum in C). The only current use
for this is replacing the nbd_set_tls (nbd, 0/1/2) parameter with
LIBNBD_TLS_DISABLE, LIBNBD_TLS_ALLOW, LIBNBD_TLS_REQUIRE (and natural
equivalents in other programming languages).
Flags maps to any uint32_t bitmask. It is basically a non-optional,
generalized
