Install a cleanup function using the trap command for signals EXIT, SIGINT, SIGQUIT and SIGABRT. The cleanup function will perform: 1. Online the CPUs that were made offline during the test. 2. Removing the cgroups created. 3. Restoring the original /sys/kernel/debug/sched/verbose value, currently it's left turned on, irrespective of the original configuration value. the test performs steps 1 and 2, on the successful runs, but not during all of the failed runs. With the cleanup(), the system will perform all three steps during failed/passed test runs.
