From 966f58c2f6df826f385706673a9bb1edcfd3499a Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Tue, 6 Mar 2012 17:57:33 +0800 Subject: rcu: Remove unused srcu_barrier() The old srcu_barrier() macro is now unused. This commit removes it so that it may be used for the SRCU flavor of rcu_barrier(), which will in turn be needed to allow the upcoming call_srcu() to be used from within modules.
