If bdrv_reopen() succeeds then bs->explicit_options is updated with
the new values, but bs->options never changes.
Here's an example:
{ "execute": "blockdev-add",
"arguments": {
"driver": "qcow2",
"node-name": "hd0",
"overlap-check": "all",
"file": {
"driver": "file",
"filename": "hd0.qcow2"
}
}
}
After this, both bs->options and bs->explicit_options contain
"overlap-check": "all".
Now let's change that using qemu-io's reopen command:
(qemu) qemu-io hd0 "reopen -o overlap-check=none"
After this, bs->explicit_options contains the new value but
bs->options still keeps the old one.
This patch updates bs->options after a BDS has been successfully
reopened.
