Patch series "lib/prime_numbers: convert self-test to KUnit".
This is a clear example of a unit test.
I tested this using:
$ tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 math-prime_numbers
; KTAP version 1
; 1..1
; KTAP version 1
; # Subtest: math-prime_numbers
; # module: prime_numbers_kunit
; 1..1
; # prime_numbers_test: prime_numbers_test(65536) passed, last prime was 65521
; # prime_numbers_test: primes.{last=61, .sz=64, .primes[]=...x28208a20a08a28ac} = 2-3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61
;
; ok 1 prime_numbers_test
; ok 1 math-prime_numbers
This patch (of 2):
This Makefile has been dead code since it was added in commit 7fcc9b53216c
("lib/math: Add int_pow test suite"); the tests worked because of the
duplicated rules in the parent directory's Makefile. Wire up
tests/Makefile and remove the duplication.
