rl_log_control is not a kernel function - it is a utility function which is
included in programs like fsck.

If you want to trace this, you will need to use the pid provider, and also
the process you want to trace must be currently running. If so, try e.g.

# dtrace -l -n 'pid<PID>:a.out:rl_log_control:entry'
