[libnbd PATCH v4 0/4] Saner reply header layout
This was v3 patch 2/22, reworked to address the confusion about how a
structured reply header is read in two pieces before getting to the
payload portion.
I'm still working on rebasing the rest of my v3 series (patches 1,
3-22) from other comments given, but this seemed independent enough
that it's worth posting now rather than holding it up for the rest of
the series.

[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

[nbdkit PATCH 0/7] Implement structured replies in nbd plugin
I'm hoping to implement .extents for the nbd plugin; this is a
prerequisite. I'm not sure about patch 3 - if we like it, I'll
squash it to 2, if we don't, I think we are okay just dropping
it. I'm also wondering if we have to worry about malicious
plugins that don't populate the entire .pread buffer in an
effort to get nbdkit to expose portions of the heap; my patch 7
