[Qemu-devel] [PATCH v8 00/11] Support streaming to an intermediate layer |

v8:
- Rebased on top of Stefan's block branch (0a35bce416)
- The loop that pauses the block jobs in bdrv_drain_all() is now split
in two: one that iterates the list of block jobs to stop them, and
one that iterates the root bds in order to get the aio contexts.
v7: https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg02580.html
- Rebased against the current master
- Updated bdrv_drain_all() to use the new block_job_next() API.
v6: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg03046.html
- fix the no-op test following Max's suggestions
v5: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg03006.html
- Fix a few typos
- Minor documentation updates
- Update test_stream_partial() to test no-ops
- New test case: test_stream_parallel()
- New test case: test_stream_overlapping()
v4: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg01878.html
- Refactor find_block_job to use the error from bdrv_lookup_bs()
- Don't use QERR_DEVICE_IN_USE in block_job_create() since we can be
dealing with nodes now.
- Fix @device comment in the BlockJobInfo documentation
- stream_start(): simplify the bdrv_reopen() call and use
bdrv_get_device_or_node_name() for error messages.
- Use a different variable name for BlockDriverState *i
- Documentation fixes in docs/live-block-ops.txt
- Update iotest 30 since now test_device_not_found() returns
GenericError
- Fix test case test_stream_partial()
- Add new test case test_stream_intermediate()
- Fix typos
v3: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg00806.html
- Keep a list of block jobs and make qmp_query_block_jobs() iterate
over it.
v2: https://lists.gnu.org/archive/html/qemu-devel/2015-03/msg04798.html
- The 'block-stream' command does not have a 'node-name' parameter
anymore and reuses 'device' for that purpose.
- Block jobs can now be owned by any intermediate node, and not just
by the ones at the root. query-block-jobs is updated to reflect that
change.
- The 'device' parameter of all 'block-job-*' commands can now take a
node name.
- The BlockJobInfo type and all BLOCK_JOB_* events report the node
name in the 'device' field if the node does not have a device name.
- All intermediate nodes are blocked (and checked for blockers) during
the streaming operation.
