Available as a tag at:
git fetch git://repo.or.cz/qemu/ericb.git nbd-blkdebug-v9

Prerequisite: Max's block-next tree:
https://lists.gnu.org/archive/html/qemu-devel/2017-04/msg01298.html

v6 was:
https://lists.gnu.org/archive/html/qemu-devel/2017-03/msg01562.html
v7 and v8 were the first half of v6, and already applied to 2.9,
at commit f82c5b17.

Since then:
- Rebase to master
- Add more qcow2 patches to make write zeroes at unaligned tail cluster
more like discard of the same cluster, including more tests
