Ah that makes sense, the tests should work (in the sense that they should not fail) on eg 5.15-stable, but I guess the 5.14 kernel is something else entirely? Most of them would return 77 on older kernels where a specific feature is missing, but eg pipe-bug.t should definitely run and pass on older kernels. -- Jens Axboe
