[Bug runtime/10605] New: Unknown symbol in module error (Unknown symbol si_swapinfo)

["wangkai at noahsi dot com dot cn" <sourceware-bugzilla at sourceware dot org>]

I have this script.
#cat test.stp
%{
#include <linux/swap.h>
%}

function get_swap_total:long()
%{
        struct sysinfo i;
        si_swapinfo(&i);
        THIS->__retvalue = i.totalswap;

%}

probe timer.s(1)
{
        printf("%d\n", get_swap_total())
        exit()
}

Errors I get are,
#stap -v -g test.stp

How to call this function(si_swapinfo)?

Thanks,
