		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
		second invocation sets the fields to comm,tid,time,sym. In this case a
		second invocation sets the fields to comm,tid,time,ip,sym. In this case a
		warning is given to the user:

		"Overriding previous field request for all events."

		Alternativey, consider the order:

		-f comm,tid,time,sym -f trace:
		-f comm,tid,time,ip,sym -f trace:

		The first -f sets the fields for all events and the second -f
		suppresses trace events. The user is given a warning message about
