Hmm, seems, you didn't use scripts/get_maintainer.pl, as neither Eric nor John 
are in Cc. Add them.

This new migration parameter allows mapping block node names and bitmap
names to aliases for the purpose of block dirty bitmap migration.

This way, management tools can use different node names on the source
and destination and pass the mapping of how bitmaps are to be
transferred to qemu (on the source, the destination, or even both with
arbitrary aliases in the migration stream).

v1 (as opposed to the RFC):
- Added an iotest
- Allow mapping of not only node names, but also of bitmap names to
- Make this a migration parameter instead of adding a whole new QMP
- Added patch 1 for good measure

Max Reitz (4):
   migration: Prevent memleak by ...params_test_apply
   migration: Add block-bitmap-mapping parameter
   iotests.py: Add wait_for_runstate()
   iotests: Test node/bitmap aliases during migration
