From 61cfd0970ea27764434fba5c41bdaefb26c44183 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 2 Sep 2014 12:30:58 -0700 Subject: rcu: Move RCU_BOOST variable declarations, eliminating #ifdef There are some RCU_BOOST-specific per-CPU variable declarations that are needlessly defined under #ifdef in kernel/rcu/tree.c. This commit therefore moves these declarations into a pre-existing #ifdef in kernel/rcu/tree_plugin.h. Signed-off-by: Paul E.
