[PATCH nbdkit 0/7] server: Implement NBD_FLAG_CAN_MULTI_CONN.
First thing to say is that I need to do a *lot* more testing on this,
so this is just an early peek. In particular, although it passed
‘make check && make check-valgrind’ I have *not* tested it against a
multi-conn-aware client such as the Linux kernel >= 4.9.
This implements NBD_FLAG_CAN_MULTI_CONN, described in the protocol doc
as:
"NBD_FLAG_CAN_MULTI_CONN: Indicates that

[PATCH nbdkit v2 01/11] server: Implement NBD_FLAG_CAN_MULTI_CONN.
For existing commits, this is almost identical to v1, except that I
updated some commit messages and reordered the commits in a somewhat
more logical sequence.
The main changes are the extra commits:
[06/11] plugins: Return NBD_FLAG_CAN_MULTI_CONN from some readonly plugins.
- Readonly plugins that can set the flag unconditionally.
[09/11] partitioning: Return NBD_FLAG_CAN_MULTI_CONN.

[nbdkit PATCH 0/9] RFC: implement NBD_CMD_CACHE
I'm still working my way through the filters before this series will
be complete, but this is enough of a start to at least get some
feedback on the idea of implementing another NBD protocol extension.

server: Internal hooks for implementing NBD_CMD_CACHE
plugins: Add .cache callback
file, split: Implement .cache with posix_fadvise
nbd: Implement NBD_CMD_CACHE

[nbdkit PATCH 0/9] can_FOO caching, more filter validation
It's easy to use the sh script to demonstrate that nbdkit is
inefficiently calling into .get_size, .can_fua, and friends more than
necessary. We've also commented on the list in the past that it would
be nice to ensure that when filters call into next_ops, they are not
violating constraints (as we've have to fix several bugs in the past
where we did not have such checking to protect

[nbdkit PATCH v2 00/24] implement NBD_CMD_CACHE
Since v1:
- rework .can_cache to be tri-state, with default of no advertisement
(ripple effect through other patches)
- add a lot more patches in order to round out filter support
And in the meantime, Rich pushed NBD_CMD_CACHE support into libnbd, so
in theory we now have a way to test cache commands through the entire
stack.

[PATCH nbdkit v5 FINAL 00/19] Implement extents.
This has already been pushed upstream. I am simply posting these here
so we have a reference in the mailing list in case we find bugs later
(as I'm sure we will - it's a complex patch series).
Great thanks to Eric Blake for tireless review on this one. It also
seems to have identified a few minor bugs in qemu along the way.
Rich.
