From: Paul E. McKenney on 5 Apr 2010 14:40 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 b/include/linux/rcupdate.h | 15 ++++++----- b/include/linux/rcutiny.h | 12 ++++++++- b/include/linux/rcutree.h | 2 + b/include/linux/srcu.h | 4 +-- b/kernel/rcupdate.c | 19 -------------- b/kernel/rcutiny.c | 9 +----- b/kernel/rcutiny_plugin.h | 39 ++++++++++++++++++++++++++++++ b/kernel/rcutree.c | 10 +++++++ b/kernel/rcutree_plugin.h | 2 - b/kernel/sched.c | 2 - b/kernel/softirq.c | 2 - include/linux/rcupdate.h | 12 +++------ include/linux/rcutiny.h | 17 +++++++++++++ include/linux/rcutree.h | 4 +++ kernel/rcutiny.c | 20 ++++++++++----- kernel/rcutree.c | 58 ++++++++++++++++++++++++++++++++------------- kernel/rcutree_plugin.h | 11 +++++--- 17 files changed, 166 insertions(+), 72 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
