Linux statfs/statfs64 结构体（RISC-V 64位）

重要: 此结构体必须与 Linux 内核定义完全一致

参考：include/uapi/asm-generic/statfs.h

§字段说明

f_type: 文件系统类型魔数（使用 FileSystemType 枚举）
f_bsize: 最优传输块大小
f_blocks: 文件系统总块数
f_bfree: 空闲块数
f_bavail: 非特权用户可用块数
f_files: 总 inode 数
f_ffree: 空闲 inode 数
f_fsid: 文件系统 ID
f_namelen: 最大文件名长度
f_frsize: 片段大小
f_flags: 挂载标志（MountFlags）
f_spare: 保留字段（填充）
