function::probefunc - Return the probe point's function name, if known

       None

       This function returns the name of the function being probed based on the current address, as computed by
       symname(addr) or usymname(uaddr) depending on probe context (whether the probe is a user probe or a
       kernel probe).

       function::probefunc - Return the probe point's function name, if known

       this function's behaviour differs between SystemTap 2.0 and earlier versions. Prior to 2.0, probefunc
       obtained the function name from the probe point string as returned by pp, and used the current address as
       a fallback.

       Consider using ppfunc instead.
