Thanx, Paul ------------------> Lai Jiangshan (4) rcu: optionally leave lockdep enabled after RCU lockdep splat rcu: make dead code really dead rcu: move some code from macro to function rcu: ignore offline CPUs in last non-dyntick-idle CPU check Paul E. McKenney (17) rcu: substitute set_need_resched for sending resched IPIs rcu: Fix bogus CONFIG_PROVE_LOCKING in comments to reflect reality. rcu: fix now-bogus rcu_scheduler_active comments. rcu: shrink rcutiny by making synchronize_rcu_bh() be inline rcu: rename rcutiny rcu_ctrlblk to rcu_sched_ctrlblk rcu: refactor RCU's context-switch handling rcu: slim down rcutiny by removing rcu_scheduler_active and friends rcu: enable CPU_STALL_VERBOSE by default rcu: disable CPU stall warnings upon panic rcu: print boot-time console messages if RCU configs out of ordinary rcu: improve RCU CPU stall-warning messages rcu: permit discontiguous cpu_possible_mask CPU numbering rcu: reduce the number of spurious RCU_SOFTIRQ invocations rcu: improve the RCU CPU-stall warning documentation rcu: make SRCU usable in modules rcu: RCU_FAST_NO_HZ must check RCU dyntick state rcu: fix build bug in RCU_FAST_NO_HZ builds Documentation/RCU/stallwarn.txt | 94 ++++++++++++++++++++++------- Documentation/RCU/trace.txt | 35 +++++------ include/linux/rcupdate.h | 42 +++++++------ include/linux/rcutiny.h | 29 ++++++++- include/linux/rcutree.h | 6 + include/linux/srcu.h | 6 + kernel/lockdep.c | 3 kernel/rcupdate.c | 19 ----- kernel/rcutiny.c | 29 +++++---- kernel/rcutiny_plugin.h | 39 ++++++++++++ kernel/rcutree.c | 127 ++++++++++++++++++++++++++++------------ kernel/rcutree.h | 2 kernel/rcutree_plugin.h | 67 ++++++++++++++++++--- kernel/rcutree_trace.c | 4 - kernel/sched.c | 2 kernel/softirq.c | 2 lib/Kconfig.debug | 14 ++++ 17 files changed, 381 insertions(+), 139 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/ |
