lib/test: convert test_sort.c to use KUnit This follows up commit ebd09577be6c ("lib/test: convert lib/test_list_sort.c to use KUnit"). Converting this test to KUnit makes the test a bit shorter, standardizes how it reports pass/fail, and adds an easier way to run the test [1]. Like ebd09577be6c, this leaves the file and Kconfig option name the same, but slightly changes their dependencies (needs CONFIG_KUNIT).

lib/test_sort: add a testcase to ensure code coverage The addition of an if statement in lib/sort to handle the final unsorted 2 or 3 elements is not covered by existing test cases, leading to incomplete test coverage. To ensure comprehensive testing and maintain 100% code coverage, add a new testcase for scenarios where the if statement is triggered. Since the if statement is only triggered when the array length is odd and the first element is greater than the second element, a testcase is created using an array length of TEST_LEN - 1 and a suitable random seed to maintain full code coverage.

lib/test_sort.c: add module unload support test_sort.c performs array-based and linked list sort test. Code allows to compile either as a loadable modules or builtin into the kernel. Current code is not allow to unload the test_sort.ko module after successful completion. This patch adds support to unload the "test_sort.ko" module by adding module_exit support. Previous patch was implemented auto unload support by returning -EAGAIN from module_init() function on successful case, but this approach is not ideal. The auto-unload might seem like a nice optimization, but it encourages inconsistent behaviour. And behaviour that is different from all other normal modules.

Revert "lib/test_sort.c: make it explicitly non-modular" Patch series "lib: add module support to sort tests". This patch series allows to compile the array-based and linked list sort test code either to loadable modules, or builtin into the kernel. It's very valuable to have modular tests, so you can run them just by insmodding the test modules, instead of needing a separate kernel that runs them at boot. This patch (of 3): This reverts commit 8893f519330bb073a49c5b4676fce4be6f1be15d. It's very valuable to have modular tests, so you can run them just by insmodding the test modules, instead of needing a separate kernel that runs them at boot.
