[PATCH nbdkit v4 00/15] Implement Block Status.
I'm not sure exactly which version we're up to, but let's say it's
version 4.
I'm a lot happier with this version:
- all filters have been reviewed and changed where I think that's necessary
- can_extents is properly defined and implemented now
- NBD protocol is followed
- I believe it addresses all previous review points where possible

[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

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.

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.

cross-project patches: Add NBD Fast Zero support
This is a cover letter to a series of patches being proposed in tandem
to four different projects:
- nbd: Document a new NBD_CMD_FLAG_FAST_ZERO command flag
- qemu: Implement the flag for both clients and server
- libnbd: Implement the flag for clients
- nbdkit: Implement the flag for servers, including the nbd passthrough
client
If you want to test the patches together, I've pushed a
