Hi all!
Finally, that's a proposal for new interface for filter insertion, which
provides generic way for inserting between different block graph nodes,
like BDS nodes, block exports and block devices.
v3: - add transaction support
- add test, that shows transactional filter insertion in different
cases
- drop RFC mark. I think it's now close to be a good solution. And
anyway, no comments on "RFC v2" version :) Still, I want to keep
x- prefix for now, just because there were too many different
ideas on this topic.
Vladimir Sementsov-Ogievskiy (11):
block-backend: blk_root(): drop const specifier on return type
block/export: add blk_by_export_id()
block: make bdrv_find_child() function public
block: bdrv_replace_child_bs(): move to external transaction
qapi: add x-blockdev-replace command
qapi: add x-blockdev-replace transaction action
block: bdrv_get_xdbg_block_graph(): report export ids
iotests.py: qemu_img_create: use imgfmt by default
iotests.py: introduce VM.assert_edges_list() method
iotests.py: add VM.qmp_check() helper
iotests: add filter-insertion
