/*
  this implements mappings between info levels for NTVFS backend calls

  the idea is that each of these functions implements one of the NTVFS
  backend calls in terms of the 'generic' call. All backends that use
  these functions must supply the generic call, but can if it wants to
  also implement other levels if the need arises

  this allows backend writers to only implement one varient of each
  call unless they need fine grained control of the calls.
