Jan Polensky 022245067f perf test: Ensure lock contention using pipe mode ... The 'kernel lock contention analysis test' requires reliable triggering of lock contention. On some systems, previous benchmark calls failed to generate sufficient contention due to low system activity or resource limits. This patch adds the -p (pipe) option to all calls of perf bench sched messaging, ensuring consistent lock contention without relying on socket-based communication.
