Subject: [PATCH tip/core/rcu 0/18] Torture-test updates for v5.7
Date: Fri, 14 Feb 2020 16:36:34 -0800
Message-ID: <20200215003634.GA16227@paulmck-ThinkPad-P72> (raw)

Hello!

This series contains torture-test updates.

1.	Suppress forward-progress complaints during early boot.

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
