The systemtap examines the kernel's debugging information to relate object code to source code. It works like a debugger: if you can name or place it, you can probe it. Use -\verb+kernel.function("*@net/socket.c")+ for the function entries, and -\verb+kernel.function("*@net/socket.c").return+ for the exits.
