Our goal is to help Greg with testing stable kernels, and currently the seccomp tests fail due to missing feature (seccomp ptrace hole closure) getting tested via latest kselftest. If you feel the feature isn't a stable candidate, then could you please help make the test degrade gracefully in its absence? Greatly appreciated! Thanks and best regards, Sumit
