[Qemu-devel] [PATCH v3 0/6] Support streaming to an intermediate layer

Subject: [Qemu-devel] [PATCH v3 0/6] Support streaming to an intermediate layer
Date: Wed, 8 Apr 2015 17:43:34 +0300

There's only one change in this series: there's now a list of block
jobs that is updated everytime a new one is created or destroyed.

This way we can iterate the list directly, rather than searching all
BlockDriverStates for the ones that own a block job.

Otherwise please check the summary I wrote for the previous series,
because the rest of the changes are detailed there:


- 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
- 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.



Alberto Garcia (6):
  block: keep a list of block jobs
  block: allow block jobs in any arbitrary node
  block: never cancel a streaming job without running stream_complete()
  block: Support streaming to an intermediate layer
  block: Add QMP support for streaming to an intermediate layer
