[PATCH v11 00/13] Apply COR-filter to the block-stream permanently
The iotest case test_stream_parallel still does not pass after the
COR-filter is inserted into the backing chain. As the test case may not
be initialized, it does not make a sense and was removed again.
v11:
04: Base node overlay is used instead of base.
05: Base node overlay is used instead of base.
06: New.
07: New.
08: New.
09: The new BDS-member 'supported_read_flags' is applied.
10: The 'base_metadata' variable renamed to 'base_unfiltered'.
11: New.
12: The backing-file argument is left in the QMP interface. Warning added.
13: The BDRV_REQ_COPY_ON_READ removed from the stream_populate();
The 'implicit' initialization moved back to COR-filter driver.
Base node overlay is used instead of base.
