Subject: Questions about dx --- hash conflicts and limit
Date: Tue, 31 Jul 2012 21:12:24 +0800	[thread overview]
Message-ID: <5017D9B8.5080103@gmail.com> (raw)

Dear all,

I have 2 questions about dx in ext4:

1) hash conflict

   I walked through the ext4/namei.c, but didn't find any
   code dealing with hash conflicts.

   I wonder if some name hash conflicts, how can they be stored
   and retrieved with the dir ops?

2) limit on size of dir

   For the limit on items of the dir, the dir size is limited
   to a height of 2 HTree: 
   	root node
    	  |
    intermidate node ...
    	|	|
    leaf node...

   Is this right?



Any explanations are welcomed.


thanks,
