Hello!
This series provides miscellaneous fixes:
1. Initialize and destroy rcu_synchronize only when necessary,
courtesy of Wei Yang.
2. mm/mmap.c: Add cond_resched() for exit_mmap() CPU stalls.
3. Simplify the calculation of rcu_state.ncpus, courtesy of Wei Yang.
4. Add callbacks-invoked counters.
5. Add comment documenting rcu_callback_map's purpose.
6. events: rcu: Change description of rcu_dyntick trace event,
courtesy of Madhuparna Bhowmik.
7. Grace-period-kthread related sleeps to idle priority.
8. Priority-boost-related sleeps to idle priority.
9. No-CBs-related sleeps to idle priority.
10. Expedited grace-period sleeps to idle priority.
11. fs/btrfs: Add cond_resched() for try_release_extent_mapping()
stalls.
12. Update comment from rsp->rcu_gp_seq to rsp->gp_seq, courtesy
of Lihao Liang.
13. tick/nohz: Narrow down noise while setting current task's tick
dependency, courtesy of Frederic Weisbecker.
14. Fix some kernel-doc warnings, courtesy of Mauro Carvalho Chehab.

17. Complain only once about RCU in extended quiescent state.
18. Replace 1 with true, courtesy of Jules Irenge.
19. Stop shrinker loop, courtesy of Peter Enderborg.
20. gp_max is protected by root rcu_node's lock, courtesy of Wei Yang.
21. grplo/grphi just records CPU number, courtesy of Wei Yang.
