[PATCH v6 0/7] blockdev-replace

[Vladimir Sementsov-Ogievskiy]

Hi all!

That's a non-transactional part of
"[PATCH v5 00/45] Transactional block-graph modifying API".

To simplify things, let's postpone transaction support and start from
blockdev-replace single command. That still allows to insert filters
here and there!)

That is not related and not based on recent
"[PATCH v7 0/5] block: refactor blockdev transactions". The series may
be handled in any order.

Vladimir Sementsov-Ogievskiy (7):
  block-backend: blk_root(): drop const specifier on return type
  block/export: add blk_by_export_id()
  block: make bdrv_find_child() function public
  qapi: add x-blockdev-replace command
  block: bdrv_get_xdbg_block_graph(): report export ids
  iotests.py: introduce VM.assert_edges_list() method
  iotests: add filter-insertion
