__sys is actually a variable whose type is struct cluster_info, isn't
it?

  static struct cluster_info __sys;

sd_dump_variable can be used against more things than 'state'.  We can
use it to dump any kinds of global and local variables including
integer, string, structure, array, and so on.

Perhaps, is sd_dump_expr better since what GDB actually dumps is an
expression?

Thanks,
