0x80000013 is IO_REPARSE_TAG_DEDUP. I am using Windows Server Data Dedup on this volume. (http://blogs.technet.com/b/filecab/archive/2012/05/21/introduction-to-data-deduplication-in-windows-server-2012.aspx)
So we return EINVAL
else if (rp.ReparseTag != IO_REPARSE_TAG_SYMLINK &&
rp.ReparseTag != IO_REPARSE_TAG_MOUNT_POINT){
e = EINVAL;
}
