[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.

[PATCH nbdkit v5 3/3] cache: Implement cache-max-size and cache space reclaim.
v4:
https://www.redhat.com/archives/libguestfs/2019-January/msg00032.html
v5:
 - Now we set the block size at run time.
   I'd like to say that I was able to test this change, but
   unfortunately I couldn't find any easy way to create a filesystem
   on x86-64 with a block size > 4K.  Ext4 doesn't support it at all,
   and XFS doesn't support block size > page size (and I

[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.
