Set File Information Processing

The I/O manager executes some additional checks for a subset of the information classes supported by IRP_MJ_SET_INFORMATION. Specifically, for FileRenameInformation, FileLinkInformation and FileMoveClusterInformation, the I/O manager issues an open to the parent directory of the target name to ensure that the user has access to create a child under that parent before it sends down the IRP_MJ_SET_INFORMATION request to the file system.
