[Qemu-devel] [PATCH v2 0/2] test NBD bitmap export

[Eric Blake <eblake@redhat.com>]

This is a less hacky version of my first attempt:
https://lists.gnu.org/archive/html/qemu-devel/2018-06/msg05993.html

The worst part of the hack (taking a semicolon-separated list of
requests to hand the server) is completely dropped, the member
field is renamed to reflect what it is doing, and I've added an
iotests to help us in regression testing.

I'd REALLY like to send a pull request before soft freeze (tomorrow
morning is approaching fast!) that includes these patches, so that
qemu 3.0 at least has experimental access to all the pieces needed
for playing with incremental backups.

  nbd/client: Add x-dirty-bitmap to query bitmap from server
  iotests: New test 223 for exporting dirty bitmap over NBD
