If anyone cares ...

I did the mechanics of getting Lustre 2.0.0.1 compiled and running
under SLES11SP1 (I first tried just SLES11, but it was too hard;
the kernel was just too old to make bringing the ext4 patches forward
feasible, at least for me).  I have it working right now in a small
test filesystem I use for non-production work.  It was a pain (the
major problems were in ldiskfs), but MOST of the pieces were there;
it was mostly a matter of shuffling things around and figuring out
what went where (I don't want to say it was EASY; it took a while.
But it wouldn't call it _hard_; it was mostly annoying, especially
since I wasn't that familiar at the time with ext4/ldiskfs).

I've been thinking of working with the open-source Lustre groups to get
this into a future release; perhaps I'll talk with some of them at the
upcoming LUG.
