[v3 08/10] crypto: Introduce 'detached-header' field in QCryptoBlockInfoLUKS |
Date: |
Mon, 25 Dec 2023 13:26:58 +0800 |
When querying the LUKS disk with the qemu-img tool or other APIs,
add information about whether the LUKS header is detached.
Additionally, update the test case with the appropriate
modification.
