From: John Kacur <jkacur@redhat.com> kernel/rcutorture.c:492: error: ‘synchronize_rcu_bh’ undeclared here (not in a function) synchronize_rcu_bh() is not just called as a normal function, but can also be referenced as a function pointer. When CONFIG_PREEMPT_RT_FULL is enabled, synchronize_rcu_bh() is defined as synchronize_rcu(), but needs to be defined without the parenthesis because the compiler will complain when synchronize_rcu_bh is referenced as a function pointer and not a function.
