How did you set the s_def_hash_version? Were you using debugfs? And did you turn on the dir_index feature? With recent versions of e2fsprogs the dir_index feature is enabled default, with DX_HASH_TEA as the default. > (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. Huh? What do you mean by that? Are you seeing two entries named "mnt" in the /mnt directory? I wasn't able to reproduce this. > 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 You didn't list any "mnt" entries above. So I don't know what you saw. - Ted - 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
