Ext3 users - Mar 2008 - Unable to change the 'name' field from 'ext3_dir_entry_2' structure.

Hello everybody,

I am trying to rename the file/directory by renaming the 'name' field
from ext3_dir_entry_2 structure.

I can easily do it for directories.

I am reading the structure then I change this field, and writing it back as it
is.

New file name length will be similar as the old(just for simplicity).  

But whenever I do this for file. It doesn't do any thing.

'write' sys call gets execute properly. Next time if I read dir entry
for this file it shows me older one.

Am I doing anything wrong?

#1.  *Why* are you trying to do this?

#2.  Are you doing this on an unmounted filesystem?  Or is the
     filesystem mounted when you tried to modify the filesystem directly
     using the write system call?
