[PATCH v6 0/6] Make blockdev-reopen stable

[Kevin Wolf <kwolf@redhat.com>]

This series picks up the remaining patches from Berto's series "[PATCH
v4 0/6] Allow changing bs->file on reopen", which are not merged into
master yet.

Apart from renaming 'x-blockdev-reopen' into 'blockdev-reopen', the
remaining functional change in this series is taking a list of nodes to
reopen as an argument so that multiple changes to the graph can be made
atomically that would be invalid separately (e.g. due to permission
checks on the intermediate state).

It also contains a qcow2 fix for a bug introduced by the part of the
series that was already picked up in Vladimir's "[PATCH v6 0/9] Allow
changing bs->file on reopen".

v6:
- Changed qcow2 fix to set s->data_file = NULL between .prepare and
  .commit instead of using a separate bool [Vladimir]
- Coding style fixes [Vladimir]

Alberto Garcia (4):
  block: Add bdrv_reopen_queue_free()
  block: Support multiple reopening with x-blockdev-reopen
  iotests: Test reopening multiple devices at the same time
  block: Make blockdev-reopen stable API

Kevin Wolf (2):
  qcow2: Fix dangling pointer after reopen for 'file'
  block: Acquire AioContexts during bdrv_reopen_multiple()
