[nbdkit PATCH 0/5] Add WRITE_ZEROES support
The upstream protocol recently promoted NBD_CMD_WRITE_ZEROES from
experimental to a documented extension. Exposing support for this
allows plugin writers to create sparse files when driven by a
client that knows how to use the extension; meanwhile, even if a
plugin does not support this extension, the server benefits from
less network traffic from the client.

protocol: Support

[nbdkit PATCH v3 0/4] bind .zero to Python
This cleans up the existing code base with regards to implicit
use of errno from language bindings, then rebases the previous
work in python on top of that.
I'm still playing with the perl bindings, but got further after
reading 'perldoc perlembed'.

[nbdkit PATCH v2 00/13] Add filters + FUA support to nbdkit
A combination of the work that both Rich and I have been doing
lately, where filters use only the new API with flags on every
command that the client can send over the wire (we can then
add support for more flags in nbdkit without having to add new
callbacks, as NBD adds more flags upstream).

protocol: Split flags from cmd field in requests
backend: Pass flags argument through
