I don't think so.  net/ipv4/ip_gre.c does not have support for 
modulized ipv6.  It is not so easy to fix this problem because
that code should be referenced if and only if ipv6 module is loaded 
for modulized ipv6.

To fix this, I'd like to know any method to detect whether the module 
is loaded and lock at once:

 int module_detect_and_lock(modulename_t *module){
   module_t *module
   if (module = module_isloaded(module))

then, I could do this.

 if (module = module_detect_and_lock(IPV6_MODULE)){
   /* do ipv6 related things because ipv6 module is loaded. */
