Hello! This series provides a couple of updates to the RCU Tasks flavors. 1. rcu-tasks: Use order_base_2() instead of ilog2(). This spreads CPUs over queues more evenly. 2. rcu-tasks: Set ->percpu_enqueue_shift to zero upon contention. The current mainline series reduces contention by at most a factor of two. This patch gains at least another factor of eight during times of high update-side traffic. Thanx, Paul ------------------------------------------------------------------------ b/kernel/rcu/tasks.h | 6 +++--- kernel/rcu/tasks.h | 2 +- 2 files changed, 4 insertions(+), 4 deletions(-)
