Subject: [PATCH tip/core/rcu 0/17] Torture-test updates for v5.12
Date: Wed, 6 Jan 2021 09:15:32 -0800 [thread overview]
Message-ID: <20210106171532.GA20769@paulmck-ThinkPad-P72> (raw)
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.
Thanx, Paul
