Merge tag 'rcu.next.v6.10' of https://github.com/urezki/linux
Pull RCU updates from Uladzislau Rezki: - Fix a lockdep complain for lazy-preemptible kernel, remove redundant BH disable for TINY_RCU, remove redundant READ_ONCE() in tree.c, fix false positives KCSAN splat and fix buffer overflow in the print_cpu_stall_info(). - Misc updates related to bpf, tracing and update the MAINTAINERS file. - An improvement of a normal synchronize_rcu() call in terms of latency. It maintains a separate track for sync. users only. This approach bypasses per-cpu nocb-lists thus sync-users do not depend on nocb-list length and how fast regular callbacks are processed. - RCU tasks: switch tasks RCU grace periods to sleep at TASK_IDLE priority, fix some comments, add some diagnostic warning to the exit_tasks_rcu_start() and fix a buffer overflow in the show_rcu_tasks_trace_gp_kthread(). - RCU torture: Increase memory to guest OS, fix a Tasks Rude RCU testing, some updates for TREE09, dump mode information to debug GP kthread state, remove redundant READ_ONCE(), fix some comments about RCU_TORTURE_PIPE_LEN and pipe_count, remove some redundant pointer initialization, fix a hung splat task by when the rcutorture tests start to exit, fix invalid context warning, add '--do-kvfree' parameter to torture test and use slow register unregister callbacks only for rcutype test. * tag 'rcu.next.v6.10' of https://github.com/urezki/linux: (48 commits) rcutorture: Use rcu_gp_slow_register/unregister() only for rcutype test torture: Scale --do-kvfree test time rcutorture: Fix invalid context warning when enable srcu barrier testing rcutorture: Make stall-tasks directly exit when rcutorture tests end rcutorture: Removing redundant function pointer initialization rcutorture: Make rcutorture support print rcu-tasks gp state rcutorture: Use the gp_kthread_dbg operation specified by cur_ops rcutorture: Re-use value stored to ->rtort_pipe_count instead of re-reading rcutorture: Fix rcu_torture_one_read() pipe_count overflow comment rcutorture: Remove extraneous rcu_torture_pipe_update_one() READ_ONCE() rcu: Allocate WQ with WQ_MEM_RECLAIM bit set rcu: Support direct wake-up of synchronize_rcu() users rcu: Add a trace event for synchronize_rcu_normal() rcu: Reduce synchronize_rcu() latency rcu: Fix buffer overflow in print_cpu_stall_info() rcu: Mollify sparse with RCU guard rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow rcu-tasks: Fix the comments for tasks_rcu_exit_srcu_stall_timer rcu-tasks: Replace exit_tasks_rcu_start() initialization with WARN_ON_ONCE() rcu: Remove redundant CONFIG_PROVE_RCU #if condition ...
