From 53c6d4edf874d3cbc031a53738c6cba9277faea5 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 1 Jul 2014 12:22:23 -0700 Subject: rcu: Add synchronous grace-period waiting for RCU-tasks It turns out to be easier to add the synchronous grace-period waiting functions to RCU-tasks than to work around their absense in rcutorture, so this commit adds them. The key point is that the existence of call_rcu_tasks() means that rcutorture needs an rcu_barrier_tasks(). Signed-off-by: Paul E.
