Subject: [PATCH 0/1] Add KUnit tests for lib/crc16.c

Hi all,

This patch was developed during a hackathon organized by LKCAMP [1],
with the objective of writing KUnit tests, both to introduce people to
the kernel development process and to learn about different subsystems
(with the positive side effect of improving the kernel test coverage, of
course).

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! :-)
