Hello! This series provides torture-test updates, and must be applied on top of the SRCU series. 1. Add testing for RCU's global memory ordering. 2. Add debug output for wrong-CPU warning. 3. Allow summarization of verbose output. 4. Require entire stutter period be post-boot. 5. Make synctype[] and nsynctype be static global. 6. Make rcu_torture_fakewriter() use blocking wait primitives. 7. Add fuzzed hrtimer-based sleep functions. 8. Use torture_hrtimeout_jiffies() to avoid busy-waits. 9. Make stutter use torture_hrtimeout_*() functions. 10. Use hrtimers for reader and writer delays. 11. Make refscale throttle high-rate printk()s. 12. Throttle VERBOSE_TOROUT_*() output. 13. Make object_debug also double call_rcu() heap object. 14. Clean up after torture-test CPU hotplugging. 15. Maintain torture-specific set of CPUs-online books. 16. Break affinity of kthreads last running on outgoing CPU. 17. Add rcutree.use_softirq=0 to RUDE01 and TASKS01.
