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
