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 qapi/block-core.json | 62 +++++ include/block/block_int-io.h | 1 + include/block/export.h | 1 + include/sysemu/block-backend-global-state.h | 3 +- block.c | 17 ++ block/block-backend.c | 2 +- block/export/export.c | 31 +++ blockdev.c | 70 ++++- stubs/blk-by-qdev-id.c | 9 + stubs/blk-exp-find-by-blk.c | 9 + stubs/meson.build | 2 + tests/qemu-iotests/iotests.py | 17 ++ tests/qemu-iotests/tests/filter-insertion | 257 ++++++++++++++++++ tests/qemu-iotests/tests/filter-insertion.out | 5 + 14 files changed, 470 insertions(+), 16 deletions(-) create mode 100644 stubs/blk-by-qdev-id.c create mode 100644 stubs/blk-exp-find-by-blk.c create mode 100755 tests/qemu-iotests/tests/filter-insertion create mode 100644 tests/qemu-iotests/tests/filter-insertion.out -- 2.34.1
