Subject: [PATCH tip/core/rcu 0/19] New smp_call_function() torture test for v5.10
Date: Mon, 31 Aug 2020 11:07:31 -0700 [thread overview]
Message-ID: <20200831180731.GA582@paulmck-ThinkPad-P72> (raw)
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
