Subject: [PATCH tip/core/rcu 0/26] Torture-test updates for v5.14
Hello!
This series provides torture-test updates:
1. Fix remaining erroneous torture.sh instance of $*.
2. Add "scenarios" option to kvm.sh --dryrun parameter.
3. Make kvm-again.sh use "scenarios" rather than "batches" file.
4. Allow CPU hotplug to be enabled.
5. Allow CPU hotplug to be enabled.
6. Add kvm-remote.sh script for distributed rcutorture test runs.
7. Add acqrel, lock, and lock-irq.
8. Abstract read-lock-held checks.
9. Fix grace-period rate output.
10. Abstract end-of-run summary.
11. Make kvm.sh use abstracted kvm-end-run-stats.sh.
12. Make the build machine control N in "make -jN".
13. Make kvm-find-errors.sh account for kvm-remote.sh.
14. Judge RCU priority boosting on grace periods, not callbacks.
15. Correctly fetch number of CPUs for non-English languages,
courtesy of Frederic Weisbecker.
16. Set kvm.sh language to English.
17. Delay-based false positives for RCU priority boosting tests.
18. Consolidate rcu_torture_boost() timing and statistics.
19. Make rcu_torture_boost_failed() check for GP end.
20. Add BUSTED-BOOST to test RCU priority boosting tests.
21. Forgive RCU boost failures when CPUs don't pass through QS.
22. Don't count CPU-stalled time against priority boosting.
23. Make kvm-remote.sh account for network failure in pathname checks.
24. Don't cap remote runs by build-system number of CPUs.
25. Move mem_dump_obj() tests into separate function.
26. Don't penalize priority boosting when there is nothing to boost.
Thanx, Paul
