[PATCH v3 00/11] blockdev-replace

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
