From a9f4793d8900dc5dc09b3951bdcd4731290e06fe Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 2 May 2011 03:46:10 -0700 Subject: rcu: fix tracing bug thinko on boost-balk attribution The rcu_initiate_boost_trace() function mis-attributed refusals to initiate RCU priority boosting that were in fact due to its not yet being time to boost. This patch fixes the faulty comparison. Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.
