This patch series supports counter scaling when perf_evsel__read() obtains a counter using the read() system call during multiplexing.
The first patch adds scaling of counters obtained from the read() system call during multiplexing.
The second patch fixes verbose printing.
The third patch adds a test for the first patch. This patch is based on Vince's rdpmc_multiplexing.c [1]
