McKenney" To: rcu@vger.kernel.org Cc: linux-kernel@vger.kernel.org, kernel-team@meta.com, rostedt@goodmis.org Subject: [PATCH rcu 0/10] Miscellaneous fixes for v6.3 Message-ID: <20230105002257.GA1768487@paulmck-ThinkPad-P17-Gen-1> 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 miscellaneous fixes: 1. Use hlist_nulls_next_rcu() in hlist_nulls_add_tail_rcu(), courtesy of Zhao Mengmeng. 2. Consolidate initialization and CPU-hotplug code. 3. Throttle callback invocation based on number of ready callbacks. 4. Upgrade header comment for poll_state_synchronize_rcu(). 5. Make RCU_LOCKDEP_WARN() avoid early lockdep checks. 6. Suppress smp_processor_id() complaint in synchronize_rcu_expedited_wait(). 7. Make rcu_blocking_is_gp() stop early-boot might_sleep(), courtesy of Zqiang. 8. Test synchronous RCU grace periods at the end of rcu_init(). 9. Allow expedited RCU CPU stall warnings to dump task stacks. 10. Remove redundant call to rcu_boost_kthread_setaffinity(), courtesy of Zqiang.
