Public bug reported: After updating our LTP fork to 20240930 [1]
Commit ec14f45 "sched: starvation: Autocallibrate the timeout" is now causing sched:starvation test to fail. In the commit message: We also make sure to check the runtime at the end of the test because the failures could have been masked by a timeout multiplier, i.e. if you set LTP_TIMEOUT_MUL=10 the test would previously pass on a buggy kernel as well. The side efect is that we now get better PASS/FAIL messages as well. This is not a kernel regression, as we did bump the timeout multiplier for bug 2059259.
