charset="utf-8" bs->options and bs->explicit_options shouldn't contain any options for child nodes. bdrv_open_inherited() takes care to remove any options that match a child name after opening the image and the same is done when reopening. However, we miss the case of 'backing': null, which is a child option, but results in no child being created. This means that a 'backing': null remains in bs->options and bs->explicit_options. A typical use for 'backing': null is in live snapshots: blockdev-add for the qcow2 overlay makes sure not to open the backing file (because it is already opened and blockdev-snapshot will attach it). After doing a blockdev-snapshot, bs->options and bs->explicit_options become inconsistent with the actual state (bs has a backing file now, but the options still say null). On the next occasion that the image is reopened, e.g. switching it from read-write to read-only when another snapshot is taken, the option will take effect again and the node incorrectly loses its backing file. Fix bdrv_open_inherited() to remove the 'backing' option from bs->options and bs->explicit_options even for the case where it specifies that no backing file is wanted.
