The arguments are processed in the order received. A later usage can
reset a prior request. e.g.:
- -f trace: -f comm,tid,time,sym
+ -f trace: -f comm,tid,time,ip,sym
The first -f suppresses trace events (field list is ""), but then the

suppresses trace events. The user is given a warning message about
