[Qemu-devel] [PATCH 00/11] block: incremental backup transactions

[John Snow]

This series adds support for incremental backup primitives in QMP
transactions. It requires my transactionless incremental backup series.

Patch 1 adds basic support for add and clear transactions.
Patch 2 tests this basic support.

Patches 3-7 add support for error scenarios where only
some incremental backup jobs complete during a transaction.
See commits for patches #3 and #7 for more details, as these
are likely to be the most controversial additions.

Patches 8-11 test the feature added in 3-7.
