What is nt!ccpf Prefetcher trace dump


I’m looking at the pool usage on my target and getting the following output
which confused me a bit.

My questions are:

  1. What “Prefetcher trace dump” is?
  2. What does negative number of allocs mean?
  3. The number seems huge. The amount of physical memory is not even close to
    that number. Were the numbers bogus?
