McKenney" To: rcu@vger.kernel.org Cc: linux-kernel@vger.kernel.org, kernel-team@meta.com, rostedt@goodmis.org Subject: [PATCH rcu 0/13] RCU update-side scalability test updates for v6.6 Message-ID: Reply-To: paulmck@kernel.org MIME-Version: 1.0 Content-Disposition: inline Precedence: bulk List-ID: X-Mailing-List: rcu@vger.kernel.org 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.
