[Qemu-block] [PATCH v2 0/9] block/qcow2: Migration handoff fixes and cleanups

[Kevin Wolf]

This is the non-controversal part of the qcow2 locking series, which just makes
the state of images with respect to live migration clearer and fixes a few bugs
we have in the handoff procedure and with writing the qcow2 feature table.

Kevin Wolf (9):
  qcow2: Write feature table only for v3 images
  qcow2: Write full header on image creation
  block: Assert no write requests under BDRV_O_INCOMING
  block: Fix error path in bdrv_invalidate_cache()
  block: Rename BDRV_O_INCOMING to BDRV_O_INACTIVE
  block: Inactivate BDS when migration completes
  qcow2: Implement .bdrv_inactivate
  qcow2: Fix BDRV_O_INACTIVE handling in qcow2_invalidate_cache()
  qcow2: Make image inaccessible after failed qcow2_invalidate_cache()
