License copyright in modules does not match with the project License terms

I think almost all the modules have an IBM copyright saying explicitly that "all rights are reserved":
Example in nvme_gw_server.py
```
//
// Copyright (c) 2021 International Business Machines
// All rights reserved.
```

However the project license is "GNU LESSER GENERAL PUBLIC LICENSE 3"

How can live both things together?

Start with the copyright header shown in nvme_gw_server.py and compare it with the project's GNU Lesser General Public License 3 terms. Review the corresponding headers across the modules and the project license text. Done means the licensing relationship is clarified and any required project-wide wording or header changes are identified.
