Before:
  # echo 'sys_open:traceon:' > set_ftrace_filter
  # echo 'sys_close:traceoff:5' > set_ftrace_filter
  # cat set_ftrace_filter
  #### all functions enabled ####
  sys_open:traceon:unlimited

  sys_close:traceoff:count=0

After:
  # cat set_ftrace_filter
  #### all functions enabled ####
  sys_open:traceon:unlimited
  sys_close:traceoff:count=0
