AdviseFileAccessPattern is used to announce an intention to access file data with a specific pattern, allowing the kernel to perform appropriate optimizations.
pattern applies to a region starting at offset and extending for len bytes (or until end-of-file if len is 0) within the file specified by stream. The specified region need not currently exist.
The specified pattern is not binding; it merely constitutes an expectation on behalf of the application.
