All failures: https://github.com/pevik/ltp/actions/runs/14243227637/job/39917780931 Good thing is that value 5 is supported on all gcc versions we use. If clang works as well, we need just detect the compiler. Maybe it'd be easiest to test with AX_CHECK_COMPILE_FLAG. Ideally create LTP fork, enable github actions and test yourself before posting. > Hello, > I've tested the new compile options with a buggy kernel and the test can > still reproduce the issue. Martin, thanks for testing. I'm sorry to waste your time. Kind regards, Petr -- Mailing list info: https://lists.linux.it/listinfo/ltp
