  10           task has ever had available in the sysrq-T and sysrq-P debug output.

  17         help
  18           Kprobes allows you to trap at almost any kernel address and
  19           execute a callback function.  register_kprobe() establishes
  20           a probepoint and specifies the callback.  Kprobes is useful
  21           for kernel debugging, non-intrusive instrumentation and testing.
  22           If in doubt, say "N".
