Hello,

I've updated what was previously the change attribute patch for ext4 
initially posted by Alexandre Ratchov. The previous patch was 
introducing a change_attribute field, now it uses the i_version field of 
the inode.

The i_version field is a counter that is set on every inode creation and 
that is incremented every time the inode data is modified (similarly to 
the "ctime" time-stamp).
The aim is to fulfill NFSv4 requirements for rfc3530.
For the moent, the counter is only a 32bit value but it is planned to be 
64bit as required.

The patch is divided into 3 parts, the vfs layer, the ext4 specific code 
and an user part to check i_version changes via stat.


Any comments are welcome.

regards,
Jean noel
