[Qemu-devel] [PATCH v3 0/5] block: Fixes for concurrent block jobs

[Max Reitz <mreitz@redhat.com>]

I think the patches speak for themselves now.

(The title of this series alludes to what the iotest added in the final
patch tests.)


v3:
- Rebased on master
- Added two tests to test-bdrv-drain [Kevin]
- Removed new iotest from auto [Thomas]


git-backport-diff against v2:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively

001/5:[----] [--] 'block: Keep subtree drained in drop_intermediate'
002/5:[0004] [FC] 'block: Reduce (un)drains when replacing a child'
003/5:[down] 'tests: Test polling in bdrv_drop_intermediate()'
004/5:[down] 'tests: Test mid-drain bdrv_replace_child_noperm()'
005/5:[0002] [FC] 'iotests: Add test for concurrent stream/commit'


Max Reitz (5):
