Question

kernel crash while systemtap probe all kernel funciotns

// all.stp
global tar = "fork";

probe begin
{
   printf("===ready===
");     

}

probe kernel.function("*")
{
   if(execname() == tar){
        printf("%s
", ppfunc());     
   }
}

stap all.stap wait to ready. And then run the fork process. It crashed after a while.
