New series.
As I wrote in a separate e-mail, we don't need to have any additional
checks on the top image before reopening it in R/W mode since
bdrv_reopen_prepare() already takes care of checking the
BDRV_O_ALLOW_RDWR flag, which serves our purpose.
v4:
- 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.
Regards,
Berto
