We noticed there were tests for CRC32 in lib/crc32test.c and thought it would be nice to have something similar for CRC16, since it seems to be widely used in network drivers (as well as in some ext4 code). Although this patch turned out quite big, most of the LOCs come from tables containing randomly-generated test data that we use to validate the kernel's implementation of CRC-16. We would really appreciate any feedback/suggestions on how to improve this. Thanks! :-) Vinicius Peixoto (1): lib/crc16_kunit.c: add KUnit tests for crc16 lib/Kconfig.debug | 8 + lib/Makefile | 1 + lib/crc16_kunit.c | 715 ++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 724 insertions(+) create mode 100644 lib/crc16_kunit.c
