Merge tag 'rcu.2023.06.22a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull RCU updates from Paul McKenney: "Documentation updates Miscellaneous fixes, perhaps most notably: - Remove RCU_NONIDLE(). The new visibility of most of the idle loop to RCU has obsoleted this API. - Make the RCU_SOFTIRQ callback-invocation time limit also apply to the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT. - Add a jiffies-based callback-invocation time limit to handle long-running callbacks. (The local_clock() function is only invoked once per 32 callbacks due to its high overhead.) - Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs, which fixes a bug that can occur on systems with non-contiguous CPU numbering. kvfree_rcu updates: - Eliminate the single-argument variant of k[v]free_rcu() now that all uses have been converted to k[v]free_rcu_mightsleep(). - Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks too soon. Yes, this is closing the barn door after the horse has escaped, but Murphy says that there will be more horses. Callback-offloading updates: - Fix a number of bugs involving the shrinker and lazy callbacks. Tasks RCU updates Torture-test updates" * tag 'rcu.2023.06.22a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: (32 commits) torture: Remove duplicated argument -enable-kvm for ppc64 doc/rcutorture: Add description of rcutorture.stall_cpu_block rcu/rcuscale: Stop kfree_scale_thread thread(s) after unloading rcuscale rcu/rcuscale: Move rcu_scale_*() after kfree_scale_cleanup() rcutorture: Correct name of use_softirq module parameter locktorture: Add long_hold to adjust lock-hold delays rcu/nocb: Make shrinker iterate only over NOCB CPUs rcu-tasks: Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs rcu: Make rcu_cpu_starting() rely on interrupts being disabled rcu: Mark rcu_cpu_kthread() accesses to ->rcu_cpu_has_work rcu: Mark additional concurrent load from ->cpu_no_qs.b.exp rcu: Employ jiffies-based backstop to callback time limit rcu: Check callback-invocation time limit for rcuc kthreads rcu: Remove RCU_NONIDLE() rcu: Add more RCU files to kernel-api.rst rcu-tasks: Clarify the cblist_init_generic() function's pr_info() output rcu-tasks: Avoid pr_info() with spin lock in cblist_init_generic() rcu/nocb: Recheck lazy callbacks under the ->nocb_lock from shrinker rcu/nocb: Fix shrinker race against callback enqueuer rcu/nocb: Protect lazy shrinker against concurrent (de-)offloading ...
