[Qemu-devel] [PATCH v2 2.5/7] fixup! nbd-client: Refuse read-only client with BDRV_O_RDWR

[Eric Blake <eblake@redhat.com>]

...

Fix several iotests to comply with the new behavior (since
qemu-nbd of an internal snapshot, as well as nbd-server-add over QMP,
default to a read-only export, we must tell blockdev-add/qemu-io to
set up a read-only client).
