There still is a lot of patching in the VFS stuff for intents and
extends for the kernel as well as the patches to make ext3 into
ldiskfs for the lustre modules. Bits and peaces have been merged but a
lot remains to be in ext4 I believe.

Lets look at the kernel patches:

Still some way to go to get this upstream.
