Subject: [PATCH rcu 0/13] Tasks RCU updates for v5.16
Date: Wed, 15 Sep 2021 16:45:38 -0700	[thread overview]
Message-ID: <20210915234538.GA3907674@paulmck-ThinkPad-P17-Gen-1> (raw)

Hello!

This series provides a number of bug fixes for RCU Tasks Trace, most
of which were uncovered in review sessions with Boqun Feng, Frederic
Weisbecker, and Neeraj Upadhyay.

1.	rcu-tasks: Wait for trc_read_check_handler() IPIs.

2.	rcu-tasks: Simplify trc_read_check_handler() atomic operations.

3.	rcu-tasks: Add trc_inspect_reader() checks for exiting critical
	section.

4.	rcu-tasks: Remove second argument of
	rcu_read_unlock_trace_special().

5.	rcu-tasks: Fix s/instruction/instructions/ typo in comment.

6.	rcu-tasks: Move RTGS_WAIT_CBS to beginning of rcu_tasks_kthread()
	loop.

7.	rcu-tasks: Fix s/rcu_add_holdout/trc_add_holdout/ typo in comment,
	courtesy of Neeraj Upadhyay.

8.	rcu-tasks: Correct firstreport usage in
	check_all_holdout_tasks_trace, courtesy of Neeraj Upadhyay.

9.	rcu-tasks: Correct comparisons for CPU numbers in
	show_stalled_task_trace, courtesy of Neeraj Upadhyay.

10.	rcu-tasks: Clarify read side section info for rcu_tasks_rude GP
	primitives, courtesy of Neeraj Upadhyay.

11.	rcu-tasks: Fix read-side primitives comment for
	call_rcu_tasks_trace, courtesy of Neeraj Upadhyay.

12.	rcu-tasks: Fix IPI failure handling in trc_wait_for_one_reader,
	courtesy of Neeraj Upadhyay.

13.	rcu-tasks: Update comments to cond_resched_tasks_rcu_qs().

						Thanx, Paul
