    tracing: replace the crude (unsigned) -1 hackery · 2c7eea4c

    Impact: cleanup
    The command line recorder uses (unsigned) -1 to mark non mapped
    entries in the pid to command line maps. The validity check is
    completely unintuitive: idx >= SAVED_CMDLINES
    There is no need for such casting games. Use a constant to mark
    unmapped entries and check for that constant to make the code readable
    and understandable.
