[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.
Eric Blake (5):
protocol: Support

[PATCH nbdkit INCOMPLETE 0/6] Introduce filters to nbdkit.
This patch isn't complete (patch 6/6 isn't finished) so it's just for
discussion, although it does compile and run.
This introduces to nbdkit a concept of "filters" which can be placed
in front of plugins to modify their behaviour. Some examples where
you might use filters:
* Serve a subset of the data, such as (offset, range) or a
single partition from a disk image.

[PATCH nbdkit filters-v3 0/7] Introduce filters.
This is still tentative and needs a lot of work, but:
- partition filter works, supporting MBR & GPT
- prepare and finalize methods fixed
- open method can now be changed (allowing readonly flag to be modified)
- thread_model can be limited
I believe I made most of the changes which were previously suggested
in email. I think the only one I didn't was preventing inclusion of
both

[PATCH nbdkit filters-v2 0/5] Introduce filters.
Rebased filters patch. Requires current git master + the locks /
thread model fix
(https://www.redhat.com/archives/libguestfs/2018-January/msg00128.html)
So a few changes here since last time:
The "introduce filters" and "implement filters" patches are
squashed together.
I introduced a concept of .prepare and .finalize. These run before
and after the data serving phase

[PATCH 0/9] Add filters to nbdkit.
The first three patches are identical to:
https://www.redhat.com/archives/libguestfs/2018-January/msg00079.html
"[PATCH nbdkit v2 0/3] Refactor plugin_* functions into a backend"
The rest of the patches add filters using the new filter API
previously described here:
https://www.redhat.com/archives/libguestfs/2018-January/msg00073.html
This needs a lot more testing -- and tests --

[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).
Eric Blake (4):
protocol: Split flags from cmd field in requests
backend: Pass flags argument through

[nbdkit PATCH v2 0/6] bind .zero to Python
Fix some things I noticed while reviewing v1, and follow Rich's
idea to add a new nbdkit_set_error() utility function with a
binding for Python users to request a particular error (rather
than being forced to live with whatever stale value is in errno
after all the intermediate binding glue code).
I could not easily find out how to register a C function callable
from perl bindings, and have
