[Qemu-block] [PATCH v2 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.


v2:
- Add comments detailing when QDicts and QLists are considered equal

git-backport-diff against v1:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
