Windows: FSCTL_SET_REPARSE_POINT error

According to MS_FSCC 2.3.54 if the input buffer length is less than the size
of a REPARSE_DATA_BUFFER structure, or the input buffer length is greater
than 16,384, or a REPARSE_DATA_BUFFER structure has been specified for a
third party reparse tag, or the GUID specified for a third party reparse tag
does not match the GUID known by the operating system for this reparse
point, or the reparse tag is 0 or 1, then the return status shall be
STATUS_IO_REPARSE_DATA_INVALID.
