[1] https://kernel.ubuntu.com/git/ubuntu/autotest-client- tests.git/commit/ubuntu_kernel_selftests/ubuntu_kernel_selftests.py?id=a381d47a9004388730e825cd20566ef102a29399 [Fix] * 1e11b7dbef17bb selftests/ftrace: Return unsupported for the unconfigured features With this patch it will be marked as unsupported, easier to understand than unresolved. This patch can be found in Groovy and newer releases, and this test does not exist in Bionic and older releases. [Test] Tested on s390x / PowerPC, this will be marked as unsupported: $ sudo ./ftracetest test.d/kprobe/kprobe_args_user.tc === Ftrace unit tests === [1] Kprobe event user-memory access [UNSUPPORTED] # of passed: 0 # of failed: 0 # of unresolved: 0 # of untested: 0 # of unsupported: 1 # of xfailed: 0 # of undefined(test bug): 0 $ echo $? 0 [Where problems could occur] Changes limited to testing tool, should not impact real kernel functionality. With this patch and local workaround in autotest-client-tests removed we might see failures in s390x / PowerPC in the future.
