Memory-Mapped file

Hi,
I have a few questions , hope to hear some suggestions from you guys.

  1. How can I differentiate between Paging IO read from VMM and memory-mapped
    file?

  2. Can I block the Paging IO read from VMM and send a new read IRP to the
    lower file system? The file system always return error status if I do that.

  3. What are the steps to disable the caching from the Cache Manager?

Thanks,
Sin-Lam
