If I understand you correctly, you can do something like this:
#undef rcu_read_lock
#define rcu_read_lock() urcu_memb_read_lock(); {
#undef rcu_read_unlock
#define rcu_read_lock() } urcu_memb_read_unlock();
(replace memb with your RCU variant of course)
and make your code declare all the RCU protected pointers inside the RCU
critical section, e.g.
rcu_read_lock();
my_pointer *foo = rcu_dereference(...);
use(foo); /* valid */
rcu_read_unlock();
use(foo); /* invalid and caught by the compiler */
