Cover letter [PATCH RFC tip/core/rcu 0/10] rcu: patches queued for 2.6.35
Hello!
RFC preview of RCU patches queued for 2.6.35:
1. substitute set_need_resched for sending resched IPIs
This reduces OS jitter.
2. make dead code really dead
3. move some code from macro to function
Cleanups from Lai Jiangshan.
4. ignore offline CPUs in last non dyntick idle CPU check
Fix to my CONFIG_RCU_FAST_NO_HZ code to handle offline and non-existent CPUs, also from Lai Jiangshan.
5. fix bogus CONFIG_PROVE_LOCKING in comments to reality
6. fix now bogus rcu_scheduler_active comments
Comment fixups.
7. shrink rcutiny by making synchronize_rcu_bh be inline
Shrink TINY_RCU some more.
8. rename rcutiny rcu_ctrlblk to rcu_sched_ctrlblk
First step towards TINY_PREEMPTIBLE_RCU.
9. refactor RCU's context switch handling
Reduce the number of needless softirqs.
10. slim down rcutiny by removing rcu_scheduler_active and friends
More shrinkage for TINY_RCU
Thanx, Paul
