22 this implements mappings between info levels for NTVFS backend calls
23
24 the idea is that each of these functions implements one of the NTVFS
25 backend calls in terms of the 'generic' call. All backends that use
26 these functions must supply the generic call, but can if it wants to
27 also implement other levels if the need arises
28
29 this allows backend writers to only implement one variant of each
30 call unless they need fine grained control of the calls.
