The point is that both the kernel and Lustre have changed enough that kernel patches are no longer needed on the client, and we are working toward removing the kernel patches on the server. At that point it would be possible to merge Lustre as an isolated (though very large) filesystem. > Boring us all with a talk why you might eventually do something to get > it merged is not productive.

What we are trying to avoid is changing all of the Lustre code, and two years from now you say "you did this completely wrong, you should do it differently". Also, there are a bunch of changes/features we have made for ext4 that we want to get merged upstream (large xattrs, stack reduction, multi-mount protection, etc). Finally, we would like to start using btrfs for a backing filesystem, and we'd like to get some discussion/consensus about the design of those changes so that they can also be accepted upstream. If you think you will be bored, you can go to the block/SCSI discussion.
