v2 was here:
https://lists.gnu.org/archive/html/qemu-devel/2020-09/msg10926.html

Since then:
rebase to master
patches 1-3/5 of v2 are in pull request
patch 4/5 in v2 (1/6 here) includes improvements from Vladimir
patches 3-6/6 here are new (and I hope to have public patches to
libnbd's 'nbdinfo --map' to take advantage of it posted soon...)

Based-on: <20201008185951.1026052-1-eblake@redhat.com>
([PULL 0/8] NBD patches through 2020-10-08)
