So, the cast is simply wrong there. Can you add a comment above that cast to explain that and make it is marked as FIXME? Because there is no guarantee that internal Linux types can be 1:1 mapped to the ABI of something. What you need, perhaps, is a middle layer function that will copy u64 data to uuid_t or so. Also, u64 is not an ABI type, why the respective __uXX variants are not in use? -- With Best Regards, Andy Shevchenko
