percpu-rw-semaphores: use rcu_read_lock_sched

2012-10-28T17:59:36Z

Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu. This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

percpu-rw-semaphores: use light/heavy barriers

2012-10-28T17:59:36Z

This patch introduces new barrier pair light_mb() and heavy_mb() for percpu rw semaphores. This patch fixes a bug in percpu-rw-semaphores where a barrier was missing in percpu_up_write. This patch improves performance on the read path of percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in percpu_up_read. This patch changes it to a compiler barrier and removes the "#if defined(X86) ..." condition. From: Lai Jiangshan Signed-off-by: Mikulas Patocka Signed-off-by: Linus Torvalds

rbtree: include linux/compiler.h for definition of __always_inline

2012-10-25T21:37:52Z

rb_erase_augmented() is a static function annotated with __always_inline. This causes a compile failure when attempting to use the rbtree implementation as a library (e.g. kvm tool): rbtree_augmented.h:125:24: error: expected `=', `,', `;', `asm' or `__attribute__' before `void' Include linux/compiler.h in rbtree_augmented.h so that the __always_inline macro is resolved correctly.
