# [40] Kprobe event auto/manual naming [UNRESOLVED]

It looks like this test exit unresolved here:

    FUNC=`grep -m 10 " [tT] .*\.isra\..*$" /proc/kallsyms | tail -n 1 | cut -f 3 -d " "`
    [ "x" != "x$FUNC" ] || exit_unresolved
    grep -n "$FUNC" available_filter_functions || exit_unresolved
    echo "p $FUNC" > kprobe_events

The FUNC here will be "show_signal.isra.0.cold", but it's not in available_filter_functions.
