firstly, with many thanks! ^-^ my problem : (1) when i want to format /dev/sda1 to be ext3-filesystem, i set "s_def_hash_version" of "struct ext3_super_block" to be "DX_HASH_LEGACY". when the filesystem was formatted successfully, i mounted it under a directory named "/mnt". (2) subsequently, i created 40000 empty regular-files under "/mnt" named from "0" to "39999". (3) then , "ls -li /mnt" was executed; i saw a puzzling thing : there are two indentical entries of the directory named "mnt"! both inode->i_ino and filename are in the same. 32203 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 24010 32204 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 24011 32205 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 24012 32206 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 24013 32207 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 24014 32208 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 24015 32209 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 24016 33220 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:37 25027 3220 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:31 3090 3350 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:31 3220 3350 -rwxrwxrwx 1 liupf liupf 0 Jun 14 11:31 3220 (4) when i change "DX_HASH_LEGACY" to be "DX_HASH_TEA", the problem listed above not happend. i scratched my head over it, failed to find any reasonable answers. :-( so, i sent my question to u and expecting eagerly some help from you. thanks again! :-) Payphone LIOU - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
