Well, '--' can be used to delineate the command portion for cases
where it's ambiguous.

Here's it's unambiguous though. This:

perf stat --repeat 20 -C 0 -ddd perf bench sched messaging -- /root/

stops parsing a valid option after the -ddd option, so in theory it
should execute 'perf bench sched messaging -- /root/' where
'-- /root/' is simply a parameter to 'perf bench' and is thus

Normally with perf commands a workload can be specified to state how long to collect perf data. That is not the case for perf-bench.
