Hello!
This series contains torture-test updates.

2. Make results-directory date format completion-friendly.
3. Refrain from callback flooding during boot.
4. Forgive -EBUSY from boottime CPU-hotplug operations.
5. Allow boottime stall warnings to be suppressed.
6. Suppress boottime bad-sequence warnings.
7. Allow disabling of boottime CPU-hotplug torture operations.
8. Add 100-CPU configuration.
9. Summarize summary of build and run results.
10. Make kvm-find-errors.sh abort on bad directory.
11. Fix rcu_torture_one_read()/rcu_torture_writer() data race.
12. Fix stray access to rcu_fwd_cb_nodelay.
13. Add READ_ONCE() to rcu_torture_count and rcu_torture_batch.
14. Annotation lockless accesses to rcu_torture_current.
15. Measure memory footprint during kfree_rcu() test.
16. Make rcu_torture_barrier_cbs() post from corresponding CPU.
17. Manually clean up after rcu_barrier() failure.
18. Set KCSAN Kconfig options to detect more data races.
Thanx, Paul
