Log:
  Trim spaces at end of line to record the proper commit message for
  r289660:
  
  Do not allow to execute ptrace(PT_TRACE_ME) when the process is
  already traced.
  
  Do not allow to execute ptrace(PT_TRACE_ME) when there is no parent
  which can trace the process, i.e. when the parent is already init.
  Note that after the PT_TRACE_ME request the process is unkillable and
  non-continuable until a debugger is attached, or parent is killed, the
  later clears P_TRACED state.  Since init clearly would not debug the
  caller, and cannot be killed, disallow creation of unkillable
  processes.
