[NTOS]
- Fix CcMdlReadComplete2 prototype.
- Fix a bug in Dominique Cote's code: when performing FsRtlGetFileSize, the length of the buffer should be set accordingly to the information class asked for, that is - FILE_STANDARD_INFORMATION structure. Previous calculation formula makes no sense at all and leads to memory corruption (if filesystem driver is stupid enough) or inability to get file size (if filesystem driver is coded by good developers).
