Cover letter [RFC] [patch 0/3] change attribute for ext4

Hello,

I've updated the change attribute patch for ext4 that was initially posted by Alexandre Ratchov.

The change attribute is a simple counter that is set on inode creation and that is incremented every time the inode data is modified (similarly to the "ctime" time-stamp) and never reset.

Here are the results of tests I ran with and without the change attribute patch.

Any comments are welcome.

regards,
Jean noel
