#     
#     Pull tracing fix from Steven Rostedt:
#      "Fix tp_printk command line and trace events
#     
#       Masami added a wrapper to be able to unhash trace event pointers as
#       they are only read by root anyway, and they can also be extracted by
#       the raw trace data buffers. But this wrapper utilized the iterator to
#       have a temporary buffer to manipulate the text with.
#     
#       tp_printk is a kernel command line option that will send the trace
#       output of a trace event to the console on boot up (useful when the
#       system crashes before finishing the boot). But the code used the same
#       wrapper that Masami added, and its iterator did not have a buffer, and
#       this caused the system to crash.
#     
#       Have the wrapper just print the trace event normally if the iterator
#       has no temporary buffer"
