Subject: [PATCH tip/core/rcu 0/13] Torture-test updates
Date: Mon, 24 Jul 2017 15:23:26 -0700 [thread overview]
Message-ID: <20170724222326.GA15933@linux.vnet.ibm.com> (raw)
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
