Subject: [PATCH rcu 0/13] RCU update-side scalability test updates for v6.6

Hello!

This series contains update-side RCU scalability tests:

1.	Permit blocking delays between writers.

2.	Add CONFIG_PREEMPT_DYNAMIC=n to NOPREEMPT scenario.

3.	Fix gp_async_max typo: s/reader/writer/.

4.	Fix uninitalized use of wait_queue_head_t, courtesy of Waiman
	Long.

5.	Add minruntime module parameter.

6.	Add a "jiffies" test.

7.	Print out full set of module parameters.

8.	Print out full set of kfree_rcu parameters.

9.	Measure grace-period kthread CPU time.

10.	Add kfree_by_call_rcu and kfree_mult to documentation.

11.	Print grace-period kthread CPU time, if recorded.

12.	Measure RCU Tasks Trace grace-period kthread CPU time.

13.	Add RCU Tasks Rude testing.

14.	fix building with RCU_TINY, courtesy of Arnd Bergmann.

15.	Move rcu_scale_writer() schedule_timeout_uninterruptible()
	to _idle(), courtesy of Zqiang.

16.	Add CONFIG_PREEMPT_DYNAMIC=n to TRACE01 scenario.

						Thanx, Paul
