Should this stub function have static inline qualifiers? All the other
stub functions in this section (ftrace_find_rec_direct,
register_ftrace_direct, unregister_ftrace_direct, modify_ftrace_direct,
and modify_ftrace_direct_nolock) use static inline. Without it, this
could cause multiple definition linker errors when the header is
included in multiple compilation units.
