> bio_check_ro() only warns about a write to a read-only disk and lets it
> through. dm-qcow2 then allocates clusters in the top image although
> the table is read-only. The header is not updated for a read-only
> table, so enabled persistent bitmaps stay marked consistent while the
> image data changes under them.
>
> Kill write requests in .clone_and_map when the table is read-only.
