Target variable that was defined by our own kernel module

["John Liang" <jliang at ibrix dot com>]

HI There,

For the following systemtap script, I run into a compiler error:

probe module("mymodule").("foobar"){
     if($myparm)
         dosomething
}

It looks if $myparm is a data structure defined in Linux Kernel,
It would compile and run without problem; but if it is a defined
by my own module, then it gave me a "unresolved symbol error for
$myparm". 

Any suggestions to solve this?

Thanks,
