thanks for the suggestion on the taskqueue. i tried it
on a dummy kernel module and got some output, but i
don't know if they were correct or not. i would like
to know
if i followed the right steps. here is the code i
used ::
struct taskqueue_arguments
{ int a;
int b;
};
void taskqueue_function(void *,int);
typedef void taskqueue_function_t(void *,int);
/* taskqueue function */
void taskqueue_function(void *arguments,int int_arg)
{
struct taskqueue_arguments *arg;
arg=(struct taskqueue_arguments *)arguments;
printf("\ntakqueue_function was called the args are
%d
%d",arg->a,arg->b);
return;
}
