Description

Running the "prefetch_io.d" dtrace script found in the zfs-test suite would result in the following error:

dtrace: failed to compile script /opt/zfs-tests/tests/perf/scripts/prefetch_io.d: line 42: aggregation redefined: @pf
    current: @pf = count( )
    previous: @pf = sum( ) : line 39

This is because the "pf" variable is being used for two different types of aggregators.
