* remotes/vsementsov/tags/pull-jobs-2021-10-07-v2:
  iotests: Add mirror-ready-cancel-error test
  mirror: Do not clear .cancelled
  mirror: Stop active mirroring after force-cancel
  mirror: Check job_is_cancelled() earlier
  mirror: Use job_is_cancelled()
  job: Add job_cancel_requested()
  job: Do not soft-cancel after a job is done
  jobs: Give Job.force_cancel more meaning
  job: @force parameter for job_cancel_sync()
  job: Force-cancel jobs in a failed transaction
  mirror: Drop s->synced
  mirror: Keep s->synced on error
  job: Context changes in job_completed_txn_abort()
  block/aio_task: assert `max_busy_tasks` is greater than 0
  block/backup: avoid integer overflow of `max-workers`
