I have also transitioned from reviewer to maintainer; however, Paul will be taking over sending RCU pull-requests for the next merge window. - Resolution of hotplug warning in nohz code, achieved by fixing cpu_is_hotpluggable() through interaction with the nohz subsystem. Tick dependency modifications by Zqiang, focusing on fixing usage of the TICK_DEP_BIT_RCU_EXP bitmask. - Avoid needless calls to the rcu-lazy shrinker for CONFIG_RCU_LAZY=n kernels, fixed by Zqiang. - Improvements to rcu-tasks stall reporting by Neeraj. - Initial renaming of k[v]free_rcu() to k[v]free_rcu_mightsleep() for increased robustness, affecting several components like mac802154, drbd, vmw_vmci, tracing, and more. A report by Eric Dumazet showed that the API could be unknowingly used in an atomic context, so we'd rather make sure they know what they're asking for by being explicit: https://lore.kernel.org/all/20221202052847.2623997-1-edumazet@google.com/ - Documentation updates, including corrections to spelling, clarifications in comments, and improvements to the srcu_size_state comments. - Better srcu_struct cache locality for readers, by adjusting the size of srcu_struct in support of SRCU usage by Christoph Hellwig. - Teach lockdep to detect deadlocks between srcu_read_lock() vs synchronize_srcu() contributed by Boqun. Previously lockdep could not detect such deadlocks, now it can. - Integration of rcutorture and rcu-related tools, targeted for v6.4 from Boqun's tree, featuring new SRCU deadlock scenarios, test_nmis module parameter, and more - Miscellaneous changes, various code cleanups and comment improvements * tag 'rcu.6.4.april5.2023.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jfern/linux: (71 commits) checkpatch: Error out if deprecated RCU API used mac802154: Rename kfree_rcu() to kvfree_rcu_mightsleep() rcuscale: Rename kfree_rcu() to kfree_rcu_mightsleep() ext4/super: Rename kfree_rcu() to kfree_rcu_mightsleep() net/mlx5: Rename kfree_rcu() to kfree_rcu_mightsleep() net/sysctl: Rename kvfree_rcu() to kvfree_rcu_mightsleep() lib/test_vmalloc.c: Rename kvfree_rcu() to kvfree_rcu_mightsleep() tracing: Rename kvfree_rcu() to kvfree_rcu_mightsleep() misc: vmw_vmci: Rename kvfree_rcu() to kvfree_rcu_mightsleep() drbd: Rename kvfree_rcu() to kvfree_rcu_mightsleep() rcu: Protect rcu_print_task_exp_stall() ->exp_tasks access rcu: Avoid stack overflow due to __rcu_irq_enter_check_tick() being kprobe-ed rcu-tasks: Report stalls during synchronize_srcu() in rcu_tasks_postscan() rcu: Permit start_poll_synchronize_rcu_expedited() to be invoked early rcu: Remove never-set needwake assignment from rcu_report_qs_rdp() rcu: Register rcu-lazy shrinker only for CONFIG_RCU_LAZY=y kernels rcu: Fix missing TICK_DEP_MASK_RCU_EXP dependency check rcu: Fix set/clear TICK_DEP_BIT_RCU_EXP bitmask race rcu/trace: use strscpy() to instead of strncpy() tick/nohz: Fix cpu_is_hotpluggable() by checking with nohz subsystem ... |
