    Subject[PATCH tip/core/rcu 0/19] New smp_call_function() torture test for v5.10
    Hello!

    This series introduces a new torture test for smp_call_function()
    and friends:

    1. Add smp_call_function() torture test.

    2. Declare parse-console.sh independence from rcutorture.

    3. Add scftorture to the rcutorture scripting.

    4. Implement weighted primitive selection.

    5. tick-sched: Clarify "NOHZ: local_softirq_pending" warning.

    6. Summarize per-thread statistics.

    7. Add smp_call_function_single() memory-ordering checks.

    8. Add smp_call_function_many() memory-ordering checks.

    9. Add smp_call_function() memory-ordering checks.

    10. Consolidate scftorture_invoke_one() check and kfree().

    11. Consolidate scftorture_invoke_one() scf_check initialization.

    12. Flag errors in torture-compatible manner.

    13. Prevent compiler from reducing race probabilities.

    14. Make symbol 'scf_torture_rand' static.

    15. Check unexpected "switch" statement value.

    16. Block scftorture_invoker() kthreads for offline CPUs.

    17. Adapt memory-ordering test to UP operation.

    18. Add cond_resched() to test loop.

    19. Change rcuperf to rcuscale.

    Thanx, Paul
