From 27f4d28057adf98750cf863c40baefb12f5b6d21 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 7 Feb 2011 12:47:15 -0800 Subject: rcu: priority boosting for TREE_PREEMPT_RCU Add priority boosting for TREE_PREEMPT_RCU, similar to that for TINY_PREEMPT_RCU. This is enabled by the default-off RCU_BOOST kernel parameter. The priority to which to boost preempted RCU readers is controlled by the RCU_BOOST_PRIO kernel parameter (defaulting to real-time priority 1) and the time to wait before boosting the readers who are blocking a given grace period is controlled by the RCU_BOOST_DELAY kernel parameter (defaulting to 500 milliseconds).
