Paul E. McKenney 3f379b03fb ftrace: Replace read_barrier_depends() with rcu_dereference_raw()
Replace the calls to read_barrier_depends() in
ftrace_list_func() with rcu_dereference_raw() to improve
readability.  The reason that we use rcu_dereference_raw() here
is that removed entries are never freed, instead they are simply
leaked.  This is one of a very few cases where use of
rcu_dereference_raw() is the long-term right answer.  And I
don't yet know of any others.  ;-)
