From e3f8d3788ed7cf55946030dc9b76e73edb111602 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 8 May 2012 10:21:50 -0700 Subject: rcu: Test srcu_barrier() from rcutorture test suite SRCU now has a call_srcu() and an srcu_barrier(), but rcutorture does not test them. This commit adds the machinery to allow rcutorture's existing tests for call_rcu() and rcu_barrier() to apply to the SRCU equivalents. Signed-off-by: Paul E.
