Subject: ask for help; hash-directory machanism of ext3 cannot work well
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.
