[Qemu-devel] [PATCH v2 0/9] block: Remove BlockDriverState.blk

[Kevin Wolf <kwolf@redhat.com>]

This is the final patch series that is required before we can start allowing
setups with more than one BlockBackend per BlockDriverState.

Depends on 'block: Move I/O throttling to BlockBackend'.

v2:
- Patch 1 ('block: Use BdrvChild callbacks for change_media/resize')
  Bring back an accidentally removed comment [Max]

- Patch 2 ('block: User BdrvChild callback for device name')
  Documented BdrvChildRole.get_name() callback [Max]

- Patch 3 ('blockjob: Don't set iostatus of target') and
  Patch 4 ('Don't touch BDS iostatus')

  Replaces 'Use BdrvChild callbacks for iostatus operations'. The whole
  problematic iostatus manipulation of block jobs only affected the target node
  where it wasn't visible, and it doesn't make sense, so it can simply go away.

- Patch 6 ('block: Add bdrv_has_blk()') and
  Patch 7 ('block: Avoid bs->blk in bdrv_next()')

  Split differently to keep the bdrv_next() changes in one patch [Max]
  Return BDSes only once in bdrv_next() even with multiple BBs [Max]
  Use enum for iteration phases instead of magic int [Max]

- Patch 9 ('block: Remove BlockDriverState.blk')
  Use bdrv_get_parent_name() to keep error message unchanged [Max]
