225  absolute limit on allocated inodes 等于cpu_to_le32(absolute limit on allocated inodes )
226  preferred inode limit 等于cpu_to_le32(preferred inode limit )
227  current # allocated inodes 等于cpu_to_le32(current # allocated inodes )
228  ime limit for excessive inode use 等于The following macros are to be defined by (ime limit for excessive inode use )
229  absolute limit on disk space (in QUOTABLOCK_SIZE) 等于cpu_to_le32(v2_stoqb(absolute limit on disk blks alloc ))

231  current space occupied (in bytes) 等于The following macros are to be defined by (current used space )
232  ime limit for excessive disk use 等于The following macros are to be defined by (ime limit for excessive disk use )
233  d this quota applies to 等于cpu_to_le32(from_kqid( & userns count is 1 for root user, 1 for init_uts_ns,* and 1 for... ?, ID this applies to (uid, gid, projid) ))
