Patch 2/4 covers this case: perf tests c2c: Report skip when the workload fails It sets err=2 before returning when the workload fails, while patch 4 calls test_c2c_function_report() only when err remains 0. I also verified this by forcing the workload command to fail. The script printed the skip message, did not run the function test, and exited with status 2, which the perf test harness treats as a skip. So I don't think any change is needed here. Thanks, Jiebin
