Hi Ingo,

thank you for testing and the patch! I've staged slightly modified 
version with few additional tests for it here: 
https://gitlab.com/cryptsetup/cryptsetup/-/tree/wip-luks2. Unfortunately 
I won't be able to test it properly due to missing access to HW. So I've 
added test for general use case w/ --master-key-file only. Can you 
please verify I didn't break it for you?

Thank you O.
