// Note that the low two bits of this code indicate the "method" in
// which the IO system uses the buffers passed by the user to
// NtFsControlFile. We use method 0--normal, buffered output (not
// DMA)--for non-API requests, and method 3--"neither" IO--for API
// requests that get processed in the server FSD. For the APIs
// that are processed in the server FSP, use method 0.
