[PATCH 0/2] Fix for write sharing on luks raw images

[Maxim Levitsky]

A rebase gone wrong, and I ended up allowing a luks image
to be opened at the same time by two VMs without any warnings/overrides.

Fix that and also add an iotest to prevent this from happening.

Best regards,
        Maxim Levisky
