From 2fdbb31b662787f78bb78b3e4e18f1a072058ffc Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 23 Feb 2012 15:58:29 -0800 Subject: rcu: Add RCU_FAST_NO_HZ tracing for idle exit Traces of rcu_prep_idle events can be confusing because rcu_cleanup_after_idle() does no tracing. This commit therefore adds this tracing. Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.
