Hello! This series provides miscellaneous fixes: 1. Remove KCSAN stubs from tree.c. 2. Remove KCSAN stubs from update.c. 3. Remove KCSAN stubs from srcutree.c. 4. Initialize at declaration time in rcu_exp_handler(). 5. rcu/trace: Print negative GP numbers correctly. 6. rcu/trace: Use gp_seq_req in acceleration's rcu_grace_period tracepoint. 7. Clarify RCU nocb CPU error message. 8. rcu/tree: Force quiescent state on callback overload. 9. rcu/tree: Remove CONFIG_PREMPT_RCU check in force_qs_rnp(). 10. Remove show_rcu_nocb_state() false positive printout. 11. Add READ_ONCE() to rcu_do_batch() access to rcu_divisor. 12. Add READ_ONCE() to rcu_do_batch() access to rcu_resched_ns. 13. Add READ_ONCE() to rcu_do_batch() access to rcu_kick_kthreads. 14. Add READ_ONCE() to rcu_do_batch() access to rcu_cpu_stall_ftrace_dump. 15. Fix kerneldoc comments in rcupdate.h. 16. Introduce list/hlist_for_each_entry_srcu() macros. 17. mmu: page_track: Fix RCU list API usage. 18. Move rcu_cpu_started per-CPU variable to rcu_data. 19. rcu/nocb: Add a warning for non-GP kthread running GP code. 20. Clarify comments about FQS loop reporting quiescent states. 21. Make FQS more aggressive in complaining about offline CPUs. 22. Remove unused __rcu_is_watching() function. 23. rcu/segcblist: Prevent useless GP start if no CBs to accelerate. 24. Shrink each possible cpu krcp.
