Let's mark it with KUNIT_CASE_SLOW which reports now as: # kasan_atomics.speed: slow Link: https://lkml.kernel.org/r/20241101184011.3369247-3-snovitoll@xxxxxxxxx Signed-off-by: Sabyrzhan Tasbolatov <snovitoll@xxxxxxxxx> Cc: Alexander Potapenko <glider@xxxxxxxxxx> Cc: Andrey Konovalov <andreyknvl@xxxxxxxxx> Cc: Andrey Ryabinin <ryabinin.a.a@xxxxxxxxx> Cc: Dmitry Vyukov <dvyukov@xxxxxxxxxx> Cc: Marco Elver <elver@xxxxxxxxxx> Cc: Vincenzo Frascino <vincenzo.frascino@xxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/kasan/kasan_test_c.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/mm/kasan/kasan_test_c.c~kasan-change-kasan_atomics-kunit-test-as-kunit_case_slow +++ a/mm/kasan/kasan_test_c.c @@ -2075,7 +2075,7 @@ static struct kunit_case kasan_kunit_tes KUNIT_CASE(kasan_strings), KUNIT_CASE(kasan_bitops_generic), KUNIT_CASE(kasan_bitops_tags), - KUNIT_CASE(kasan_atomics), + KUNIT_CASE_SLOW(kasan_atomics), KUNIT_CASE(vmalloc_helpers_tags), KUNIT_CASE(vmalloc_oob), KUNIT_CASE(vmap_tags), _ Patches currently in -mm which might be from snovitoll@xxxxxxxxx are mm-kasan-kmsan-copy_from-to_kernel_nofault.patch kasan-move-checks-to-do_strncpy_from_user.patch kasan-migrate-copy_user_test-to-kunit.patch kasan-delete-config_kasan_module_test.patch kasan-delete-config_kasan_module_test-fix.patch kasan-use-export_symbol_if_kunit-to-export-symbols.patch kasan-change-kasan_atomics-kunit-test-as-kunit_case_slow.patch
