However, it has changed to use nr_accesses_bp instead. Update the tracepoint to expose the value that DAMOS is really using. Note that it doesn't expose the value as is in the basis point, but after converting it to the natural number by dividing it by 10,000. Therefore this change doesn't make user-visible behavioral differences.
