[Qemu-block] [PATCH for-2.10 0/5] block: bdrv_reopen() fixes

[Kevin Wolf]

This is the first part of some fixes to bdrv_reopen(), which seems
reasonable enough to merge for 2.10.

There is much more wrong with bdrv_reopen() currently, especially with
respect to op blocker permissions (basically the required permissions
can change based on the options used in bdrv_reopen(), and both things
affect the whole tree and aren't integrated with each other at all), but
I have little hope to get this fixed before 2.10, so let's start with
what is ready now.

Kevin Wolf (5):
  block: Fix order in bdrv_replace_child()
  block: Allow reopen rw without BDRV_O_ALLOW_RDWR
  block: Set BDRV_O_ALLOW_RDWR during rw reopen
  qemu-io: Allow reopen read-write
  qemu-iotests: Test reopen between read-only and read-write
