    [snapshot][api] Expose the snapshot checksum as crash key · 35fc0c17
    Camillo Bruni authored
    Due to the consistent overhead of snapshot checksum verification
    we ideally want to avoid it all-together. However there are still enough
    devices out there that suffer from corrupted snapshots that might
    cause hard to debug heap corruptions.
    
    This CL exposes the calculated (dummy value for now) and the expected
    snapshot checksum as a crash key, so it can be easily consulted during
    investigation.
    
    Note: The calculated crash key contains 0x0 for now as a dummy value. We
    will come up with a strategy later-on to limit the overhead of
    calculating the checksum.
