[PATCH v10 0/9] Apply COR-filter to the block-stream permanently |

Despite the patch "freeze link to base node..." has been removed from the
series in the current version 9, the iotest case test_stream_parallel 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.
The check with bdrv_is_allocated_above() takes place in the COR-filter and
in the block-stream job both. An optimization of the block-stream job based
on the filter functionality may be made in a separate series.
v10:
02: The missed new file block/copy-on-read.h added
v9:
02: Refactored.
04: Base node name is used instead of the file name.
05: New implementation based on Max' review.
06: New.
07: New. The patch "freeze link to base node..." was deleted.
08: New.
09: The filter node options are initialized.
The v8 Message-Id:
<1598633579-221780-1-git-send-email-andrey.shinkevich@virtuozzo.com>
Andrey Shinkevich (9):
copy-on-read: Support preadv/pwritev_part functions
copy-on-read: add filter append/drop functions
qapi: add filter-node-name to block-stream
copy-on-read: pass base node name to COR driver
copy-on-read: limit guest COR activity to base in COR driver
copy-on-read: skip non-guest reads if no copy needed
stream: skip filters when writing backing file name to QCOW2 header
block: remove unused backing-file name parameter
block: apply COR-filter to block-stream jobs
