   3 # Check the console output from an rcutorture run for goodness.
   4 # The "file" is a pathname on the local system, and "title" is
   5 # a text string for error-message purposes.
   6 #
   7 # The file must contain rcutorture output, but can be interspersed
   8 # with other dmesg text.
   9 #
  10 # Usage:
  11 #       sh parse-rcutorture.sh file title
