| |
Hello!
Now that there is only one rcu_data structure per CPU, there isn't a whole lot of point in maintaining a separate per-CPU rcu_dynticks structure. This series therefore merges the rcu_dynticks structure into the rcu_data structure.
1. Remove unused rcu_dynticks_snap() from Tiny RCU.
2. Merge rcu_dynticks structure into rcu_data structure, but continue using the rcu_dynticks structure's fields.
3-8. Change the code to use the fields in the rcu_data structure instead of those in the rcu_dynticks structure.
9. Remove the now-obsolete ->dynticks_fqs and ->cond_resched_completed fields from the rcu_data structure.
10. Convert rcu_state.ofl_lock to raw_spinlock_t to make -rt feel better, courtesy of Mike Galbraith.
Thanx, Paul
