Weird Probe points on PPC

Hi Guys, 

I found something that I can't explain in SystemTap.
When probing module("jsm").function("*) it is probing more
function that those inside the jsm module (ie, out_8, in_8, writeb, etc)

At the same time, if I probe module("jsm").function("*").return
it works properly. Did anyone see anything like that ?


kernel: 2.6.31-rc8-ppc64
stap version: version 0.9.9/0.142.90 commit release-0.9.9-319-ge08217d + changes


----- jsm.stp -----
probe module("jsm").function("*"){
	printf("-> %s\n",  probefunc())
}


probe module("jsm").function("*").return {
	printf("<- %s\n",  probefunc())
}


---- output -----
