[Qemu-block] [PATCH 0/4] block: Don't compare strings in bdrv_reopen_prepare()

[Max Reitz]

bdrv_reopen_prepare() assumes that all BDS options are strings, which is
not necessarily correct. This series introduces a new qobject_is_equal()
function which can be used to test whether any options have changed,
independently of their type.


Max Reitz (4):
  qapi/qnull: Add own header
  qapi: Add qobject_is_equal()
  block: qobject_is_equal() in bdrv_reopen_prepare()
  iotests: Add test for non-string option reopening
