Re: [PATCH v3 6/7] qapi/block-core: deprecate block-job-change

That's a first step to move on newer job-* APIs. The difference between block-job-change and job-change is in find_block_job_locked() vs find_job_locked() functions. What's different? 1. find_block_job_locked() finds only block jobs, whereas find_job_locked() finds any kind of job. job-change is a compatible extension of block-job-change. 2. find_block_job_locked() reports DeviceNotActive on failure, when find_job_locked() reports GenericError. Since the kind of error reported isn't documented for either command, and clients shouldn't rely on undocumented error details, job-change is a compatible replacement for block-job-change.
