[PATCH v2 5/7] qapi: add job-change
Posted by Vladimir Sementsov-Ogievskiy 5 months ago
Add a new-style command job-change, doing same thing as
block-job-change. The aim is finally deprecate block-job-* APIs and
move to job-* APIs.

We add a new command to qapi/block-core.json, not to
qapi/job.json to avoid resolving json file including loops for now.
This all would be a lot simple to refactor when we finally drop
deprecated block-job-* APIs.

@type argument of the new command immediately becomes deprecated.

Oops, that type-based union was dropped, so this sentence should be dropped as well.
