| |
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.
Thanx, Paul
