8901ac9d2c7eb8ed7ae5e749bf13ecb3b6062488 - printf: Compile the kunit test with DISABLE_BRANCH_PROFILING DISABLE_BRANCH_PROFILING

Tue, 14 Apr 2026 17:41:24 +0200

printf: Compile the kunit test with DISABLE_BRANCH_PROFILING DISABLE_BRANCH_PROFILINGGCC < 12.1 can miscompile printf_kunit's errptr() test when branchprofiling is enabled. BUILD_BUG_ON(IS_ERR(PTR)) is a constant falseexpression, but CONFIG_TRACE_BRANCH_PROFILING andCONFIG_PROFILE_ALL_BRANCHES make the IS_ERR() path side-effectful.GCC's IPA splitter can then outline the cold assert arm intoerrptr.part.* and leave that clone with an unconditional__compiletime_assert_*() call, causing a false build failure.This started showing up after test_hashed() became a macro and moved itslocal buffer into errptr(), which changed GCC's inlining and splittingdecisions enough to expose the compiler bug.Workaround the problem by disabling the branch profiling forprintf_kunit.o. It is a straightforward and acceptable solution.The workaround can be removed once the minimum GCC includes commit76fe49423047 ("Fix tree-optimization/101941: IPA splitting outfunction with error attribute"), which first shipped in GCC 12.1.Fixes: 9bfa52dac27a ("printf: convert test_hashed into macro")Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202604030636.NqjaJvYp-lkp@intel.com/Cc: stable@vger.kernel.orgAcked-by: Tamir Duberstein Link: https://patch.msgid.link/ad5gJAX9f6dSQluz@pathway.suse.czSigned-off-by: Petr Mladek List of files: /linux/lib/tests/Makefile

4101b3b571701cdf1081b2f96124b1daaeaebbf1 - lib/tests: add KUnit test for bitops

Sat, 10 Jan 2026 18:38:07 +0100

lib/tests: add KUnit test for bitopsAdd a KUnit test suite for the bitops API.The existing 'lib/test_bitops.c' is preserved as-is because it containsad-hoc micro-benchmarks 'test_fns' and is intended to ensure no compilerwarnings from C=1 sparse checker or -Wextra compilations.Introduce 'lib/tests/bitops_kunit.c' for functional regression testing. Itports the test logic and data patterns from 'lib/test_bitops.c' to KUnit,verifying correct behavior across various input patterns andarchitecture-specific edge cases using isolated stack-allocated bitmaps.The following test logic has been ported from test_bitops_startup() inlib/test_bitops.c:- set_bit() / clear_bit() / find_first_bit() validation -> test_set_bit_clear_bit()- get_count_order() validation -> test_get_count_order()- get_count_order_long() validation -> test_get_count_order_long()Also improve the find_first_bit() test to check the full bitmap length(BITOPS_LENGTH) instead of omitting the last bit, ensuring the bitmap iscompletely empty after cleanup.Verified on x86_64, i386, and arm64 architectures.Sample KUnit output: KTAP version 1 # Subtest: bitops # module: bitops_kunit 1..3 KTAP version 1 # Subtest: test_set_bit_clear_bit ok 1 BITOPS_4 ok 2 BITOPS_7 ok 3 BITOPS_11 ok 4 BITOPS_31 ok 5 BITOPS_88 # test_set_bit_clear_bit: pass:5 fail:0 skip:0 total:5 ok 1 test_set_bit_clear_bit KTAP version 1 # Subtest: test_get_count_order ok 1 0x00000003 ok 2 0x00000004 ok 3 0x00001fff ok 4 0x00002000 ok 5 0x50000000 ok 6 0x80000000 ok 7 0x80003000 # test_get_count_order: pass:7 fail:0 skip:0 total:7 ok 2 test_get_count_order KTAP version 1 # Subtest: test_get_count_order_long ok 1 0x0000000300000000 ok 2 0x0000000400000000 ok 3 0x00001fff00000000 ok 4 0x0000200000000000 ok 5 0x5000000000000000 ok 6 0x8000000000000000 ok 7 0x8000300000000000 # test_get_count_order_long: pass:7 fail:0 skip:0 total:7 ok 3 test_get_count_order_long[Yury: trim Kconfig help message]CC: Jesse Brandeburg CC: Wei Yang Signed-off-by: Ryota Sakamoto Signed-off-by: Yury Norov List of files: /linux/lib/tests/Makefile

lib/glob: convert selftest to KUnitThis patch converts the existing glob selftest (lib/globtest.c) to use theKUnit framework (lib/tests/glob_kunit.c).The new test:- Migrates all 64 test cases from the original test to the KUnit suite.- Removes the custom 'verbose' module parameter as KUnit handles logging.- Updates Kconfig.debug and Makefile to support the new KUnit test.- Updates Kconfig and Makefile to remove the original selftest.- Updates GLOB_SELFTEST to GLOB_KUNIT_TEST for arch/m68k/configs.This commit is verified by `./tools/testing/kunit/kunit.py run'with the .kunit/.kunitconfig:CONFIG_KUNIT=yCONFIG_GLOB_KUNIT_TEST=yLink: https://lkml.kernel.org/r/20260108120753.27339-1-note351@hotmail.comSigned-off-by: Kir Chou Acked-by: Geert Uytterhoeven Reviewed-by: David Gow Reviewed-by: Kuan-Wei Chiu Cc: Signed-off-by: Andrew Morton List of files: /linux/lib/tests/Makefile

lib/tests: convert test_min_heap module to KUnitMove lib/test_min_heap.c to lib/tests/min_heap_kunit.c and convert it touse KUnit.This change switches the ad-hoc test code to standard KUnit test cases. The test data remains the same, but the verification logic is updated touse KUNIT_EXPECT_* macros.Also remove CONFIG_TEST_MIN_HEAP from arch/*/configs/* because it is nolonger used. The new CONFIG_MIN_HEAP_KUNIT_TEST will be automaticallyenabled by CONFIG_KUNIT_ALL_TESTS.The reasons for converting to KUnit are:1. Standardization: Switching from ad-hoc printk-based reporting to the standard KTAP format makes it easier for CI systems to parse and report test results2. Better Diagnostics: Using KUNIT_EXPECT_* macros automatically provides detailed diagnostics on failure.3. Tooling Integration: It allows the test to be managed and executed using standard KUnit tools.Link: https://lkml.kernel.org/r/20251221133516.321846-1-sakamo.ryota@gmail.comSigned-off-by: Ryota Sakamoto Acked-by: Kuan-Wei Chiu Cc: Alexander Gordeev Cc: Christian Borntraeger Cc: David Gow Cc: Geert Uytterhoeven Cc: Heiko Carstens Cc: Madhavan Srinivasan Cc: Michael Ellerman Cc: Nicholas Piggin Cc: Sven Schnelle Cc: Vasily Gorbik Signed-off-by: Andrew Morton List of files: /linux/lib/tests/Makefile
