[PATCH nbdkit 0/3] filters: stats: More useful, more friendly
- Use more friendly output with GiB and MiB/s.
- Measure time per operation, providing finer grain stats
- Add missing stats for flush
I hope that these changes will help to understand and imporve virt-v2v
performance.

[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.
