[PATCH tip/core/rcu 0/13] Torture-test updates

From: Paul E. McKenney
Date: Mon Jul 24 2017 - 18:23:39 EST


Hello!

This series contains torture-test updates:

1. Move SRCU status printing to SRCU implementations.

2. Print SRCU lock/unlock totals because I am getting tired of
doing the addition in my head.

3. Remove CONFIG_TASKS_RCU ifdef from rcuperf.c.

4. Select CONFIG_PROVE_LOCKING for Tiny SRCU scenario.

5. Add --kconfig argument to kvm.sh to allow test runs to override
the test-scenario files.

6. Don't wait for kernel when all builds fail.

7. Enable SRCU readers from timer handler.

8. Place event-traced strings into trace buffer.

9. Use nr_cpus rather than maxcpus to limit test size.

10. Add task's CPU for rcutorture writer stalls.

11. Eliminate unused ts_rem local from rcu_trace_clock_local().

12. Add last-CPU to GP-kthread starvation messages.

13. Invoke call_rcu() from timer handler.

Thanx, Paul
