Your "[PATCH v2 0/3] qapi & doc: deprecate drive-backup" series contains

  docs/block-replication: use blockdev-backup
  docs/interop/bitmaps: use blockdev-backup
  qapi: deprecate drive-backup

I figure proper deprecation needs all that, i.e. we need to merge my RFC
patch into your 3/3.  Could you take care of that?
