Running the following:

 # trace-cmd start -p nop -l "*"
 # trace-cmd show --ftrace_filter |wc -l
50979
 # trace-cmd stat | wc -l
234

Shows that trace-cmd stat's listing of functions is not complete, and only shows the first 216 filters.

Perhaps its OK not to show all of them, but there should be something like the following at the end of the display:

 All disabled
