[PATCH v4 1/5] kern: dl: Allow modules under CC0 license |
Date: |
Sun, 8 Aug 2021 15:58:44 +0200 |
We're about to import the reference implementation of Argon2, which is
licensed under CC0. Given that this license is compatible with the GPL
according to [1], having code under this license alongside with GPL'd
code is perfectly fine.
