Re: [PATCH] lib: add basic KUnit test for lib/math

Add basic test coverage for files that don't require any config options:

• gcd.c
• lcm.c
• int_sqrt.c
• reciprocal_div.c

(Ignored int_pow.c since it's a simple textbook algorithm.)

These tests aren't particularly interesting, but

• they're chosen as easy to understand examples of how to write tests
• provides a place to add tests for any new files in this dir
• written so adding new test cases to cover edge cases should be easy

Is documentation not enough?

I have recently wrote my first KUnit test and I found documentation pretty good for the start. I think we actually need more complex examples in the code (and useful).

So, I'm in doubt these test are a good point to start with.
