Just checked the source code:
in fs/read_write.c:do_sendfile

 841         pos = *ppos;
 842         if (unlikely(pos + count > max)) {
 843                 retval = -EOVERFLOW;
 844                 if (pos >= max)
 845                         goto fput_out;
 846                 count = max - pos;
 847         }

and 

 869         if (*ppos > max)
 870                 retval = -EOVERFLOW;
