selftests/futex: Fix incorrect result reporting of futex_requeue test item

2026-02-04T09:51:46+00:00

When using the TEST_HARNESS_MAIN macro definition to declare the main function, it is required to use the EXPECT*() and ASSERT*() macros in conjunction and not ksft_test_result_*(). Otherwise, even if a test item fails, the test will still return a success result because ksft_test_result_*() does not affect the test harness state. Convert the code to use EXPECT/ASSERT() variants, which ensures that the overall test result is fail if one of the EXPECT()s fails. [ tglx: Massaged change log to explain _why_ ksft_test_result*() is the wrong choice ] Fixes: f341a20f6d7e ("selftests/futex: Refactor futex_requeue with kselftest_harness.h") Signed-off-by: Yuwen Chen Signed-off-by: Thomas Gleixner Link: https://patch.msgid.link/tencent_51851B741CC4B5EC9C22AFF70BA82BB60805@qq.com

selftests: complete kselftest include centralization

2025-11-27T22:24:31+00:00

This follow-up patch completes centralization of kselftest.h and ksefltest_harness.h includes in remaining seltests files, replacing all relative paths with a non-relative paths using shared -I include path in lib.mk Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on riscv, arm64, x86_64 and powerpc arch.

selftests/futex: Refactor futex_requeue with kselftest_harness.h

2025-09-20T16:11:55+00:00

To reduce the boilerplate code, refactor futex_requeue test to use kselftest_harness header instead of futex's logging header. Signed-off-by: André Almeida Signed-off-by: Thomas Gleixner

selftests: futex: Add futex compare requeue test

2021-06-22T09:20:16+00:00

Add testing for futex_cmp_requeue(). The first test just requeues from one waiter to another one, and wakes it. The second performs both wake and requeue, and checks the return values to see if the operation woke/requeued the expected number of waiters.
