[Libguestfs] [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 The "only" thing missing is it desperately needs proper tests, which is the next thing on my to-do list. So that means the patch series still isn't complete and ready for upstream, but it's certainly ready for review. Rich.
