* lib/test: convert test_sort.c to use KUnitDaniel Latypov2021-09-081-21/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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). [1] Can be run via $ ./tools/testing/kunit/kunit.py run --kunitconfig /dev/stdin <<EOF CONFIG_KUNIT=y CONFIG_TEST_SORT=y EOF [11:30:27] Starting KUnit Kernel ...

* lib/test_sort.c: add module unload supportPravin Shedge2018-02-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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"Geert Uytterhoeven2017-05-081-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lib/test_sort.c: make it explicitly non-modularPaul Gortmaker2017-02-241-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: lib/Kconfig.debug:config TEST_SORT lib/Kconfig.debug: bool "Array-based sort test" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the code there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering becomes slightly earlier when we change it to use subsys_initcall as done here. However, since it is a self contained test, this shouldn't be an issue and subsys_initcall seems like a better fit for this particular case. We also delete the MODULE_LICENSE tag since that information is now contained at the top of the file in the comments.

* lib: add CONFIG_TEST_SORT to enable self-test of sort()Kostenzer Felix2017-02-241-0/+43
Along with the addition made to Kconfig.debug, the prior existing but permanently disabled test function has been slightly refactored. Patch has been tested using QEMU 2.1.2 with a .config obtained through 'make defconfig' (x86_64) and manually enabling the option.
