finding out module name from an address ?

[Rajeev Bector]

Hi,
  I am trying to write a patched kmalloc() which
will track the caller function using 
__builtin_return_address(0). From that address,
is there a clean way to figure out if the address
belongs to a loadable module and if yes, get
to the module structure of that module so
that I can log on the basis of module->name

Thanks
Rajeev
