Pull tracing fix from Steven Rostedt:
 "Working on some new updates to trace filtering, I noticed that the
  regex_match_front() test was updated to be limited to the size of the
  pattern instead of the full test string.

  But as the test string is not guaranteed to be nul terminated, it
  still needs to consider the size of the test string"
