Changes from v1:
- Split into multiple patches
- Add "Fixes" lines to the commit messages
- Use long instead of __s64
- Ensure that the valid lifetime is not shorter than the required lifetime
- Ensure that the preferred lifetime is not longer than the valid lifetime
- Update the documentation

Thanks to David, Jiri, and Paolo for your feedback.
