Hi Andrea,

I think what Yongqiang means is that the code you are modifying is being 
removed in the patches listed above and replaced with a different 
solution.  The patches have not yet been merged so you will not see them 
in a git tree yet, so you will need to apply them yourself.  If you are 
not subscribed to the list, you can still find the patches here:

http://www.spinics.net/lists/linux-ext4/msg29109.html
http://www.spinics.net/lists/linux-ext4/msg29110.html

http://www.spinics.net/lists/linux-ext4/msg29375.html
http://www.spinics.net/lists/linux-ext4/msg29376.html

We want to make sure the solution works for everyone, so please apply 
these patches and let us know if it corrects the issues you are seeing. 
  Thx!
