Instead of providing an MBR partition type to InferFileSystem(), make it call IOCTL_DISK_GET_PARTITION_INFO(_EX) to determine whether the partition pointed by the path/handle is MBR or GPT. Then, only if it's MBR, we retrieve its partition type in order to "guess" an adequate file system name, in case the latter was not recognized already via regular ways (via GetFileSystemName() / NtQueryVolumeInformationFile()). - Remove the GetFileSystemNameByHandle() and InferFileSystemByHandle() functions. Instead, make the other GetFileSystemName*() and InferFileSystem*() functions accept a HANDLE as an alternative to the already-existing partition path string. These parameters are exclusive to each other. - Rename SetPartitionType() -> SetMBRPartitionType(), and FileSystemToPartitionType() -> FileSystemToMBRPartitionType() in order to really clarify what they do (since this code is meant for MBR partitions only, not GPT ones).
