If one picks my code, modifies it, relicenses it using GPL v3, we
can't include it anymore. It's the same story as with BSD systems and
their BSD licenses. If one picks e.g. BSD 3-clause licensed code,
makes it GPL, releases it (e.g. by putting in Linux), BSD can't use it
anymore.

Still, this license is GPL v2 compatible and as is it can be included
in the Linux.
