Progressive file layouts are characterized by increasing the
stripe count of the file in a step-wise manner as the file
offset increases. This will be achieved by using multiple
extent-based composite layouts as described in the Layout
Enhancement High Level Design:
http://wiki.lustre.org/Layout_Enhancement_High_Level_Design
This was the key item still missing in the linux lustre client.
We added this funcitonality with this patch set. With this last
key feature added this brings the linux lustre client on about
the same level as the 2.10.6 LTS. Since this is the case we can
bump the lustre version.
