Hi all!
We need to copy bitmaps to new top node on external snapshot, to
not break incremental backup chain.
The only thing to do is to allow block-dirty-bitmap-merge to work
with different nodes, here it is.
v2: use 'alternate' type in qapi for specifying source bitmap
instead of adding new field external-bitmaps [Eric]
Vladimir Sementsov-Ogievskiy (2):
qapi: support external bitmaps in block-dirty-bitmap-merge
iotests: test external snapshot with bitmap copying
