[PATCH v2 0/3] fix two edge cases related to stream block jobs

[Fiona Ebner]

Changes in v2:
    * Ran into another issue while writing the IO test Stefan wanted
      to have (good call :)), so include a fix for that and add the
      test. I didn't notice during manual testing, because I hadn't
      used a scripted QMP 'quit', so there was no race.

Fiona Ebner (2):
  block-backend: fix edge case in bdrv_next() where BDS associated to BB
    changes
  iotests: add test for stream job with an unaligned prefetch read

Stefan Reiter (1):
  block/io: accept NULL qiov in bdrv_pad_request
