[Qemu-block] [PATCH v2 00/13] qcow2: reopen: Change driver-specific runtime options

[Kevin Wolf]

This is part two of what I had sent earlier as "[PATCH 00/34] block:
Cache mode for children, reopen overhaul and more". Most of the patches
were actually already reviewed in v1.

Apart from a few addressed review comments, there are no functional
changes compared to v1. Some rebasing was necessary; also the
qemu-iotests cases are new.

Kevin Wolf (13):
  block: Allow specifying driver-specific options to reopen
  qemu-io: Remove duplicate 'open' error message
  qemu-io: Add command 'reopen'
  qcow2: Improve error message
  qcow2: Factor out qcow2_update_options()
  qcow2: Move qcow2_update_options() call up
  qcow2: Move rest of option handling to qcow2_update_options()
  qcow2: Leave s unchanged on qcow2_update_options() failure
  qcow2: Fix memory leak in qcow2_update_options() error path
  qcow2: Make qcow2_update_options() suitable for transactions
  qcow2: Support updating driver-specific options in reopen
  qemu-iotests: Reopen qcow2 with lazy-refcounts change
  qemu-iotests: More qcow2 reopen tests
