      https://github.com/XanClic/qemu child-access-functions-v6

v6:
  Re-based to the series "block: Deal with filters".
  The minimum number of patches were kept.
  Not all the iotests were checked for pass.
  
  04: The test case iotests:030:test_stream_parallel was removed
      due to multiple errors.

  copy-on-read: Support preadv/pwritev_part functions

  qapi: add filter-node-name to block-stream
