From: Paul E. McKenney Date: Tue, 21 Jun 2011 08:59:33 +0000 (-0700) Subject: rcu: Move RCU_BOOST declarations to allow compiler checking X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eab0993c7ba5c7d9b3613d6037e0f31f0ccbe181;p=linux-beck.git rcu: Move RCU_BOOST declarations to allow compiler checking Andi Kleen noticed that one of the RCU_BOOST data declarations was out of sync with the definition. Move the declarations so that the compiler can do the checking in the future. Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.
