Subject[PATCH tip/core/rcu 19/55] rcu: Move RCU_BOOST declarations to allow compiler checking
Date
From: Paul E. McKenney <paul.mckenney@linaro.org>

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.
