Hi all, We are students from the State University of Campinas with an interest in contributing to the kernel. We are part of LKCAMP, a student group that focuses on researching and contributing to open source software. Our group has organized kernel hackathons in the past [1] that resulted in sucessful contributions, and we would like to continue the effort this year. This time, we were thinking about writing KUnit tests for data structures in `lib/` (or converting existing lib test code), similarly to our previous hackathon. We are currently considering a few candidates: - lib/kfifo.c - lib/llist.c - tools/testing/scatterlist - tools/testing/radix-tree We would like to know if these are good candidates, and also ask for suggestions of other code that could benefit from having KUnit tests. Thanks! Artur Alves [1] https://lore.kernel.org/dri-devel/20211011152333.gm5jkaog6b6nbv5w@notapiano/
