[Qemu-devel] [PATCH v2 0/6] Promote x-nbd-server-add-bitmap to stable

[Eric Blake]

Or rather, move its functionality into nbd-server-add.  And as
a side effect, teach qemu-nbd how to export a persistent bitmap
without having to go through a qemu process and several QMP
commands.

[0/11 bitmaps: remove x- prefix from QMP api]

Available at: https://repo.or.cz/qemu/ericb.git nbd-bitmap-add-v2

Since v1:
- add new patch 1 allowing bitmaps with writable exports
- add coverage in iotest 223
- fix logic bug that rendered qemu-nbd -B useless
- drop support for bitmap-export-name remapping
