I guess my comments came across as negative, rather than just factual.

I would love to have XFS.  Our cluster system is "filesystem agnostic"
-- we don't need any filesystem at all(*).  Any filesystem that can be
loaded as a module can be used to dynamically enhance the system, with
no impact on the cluster architecture.  The problem is that XFS uses a
different interface, and thus can't work with a standard kernel.

(*) We actually use a ram-based filesystem to boot the cluster nodes.
But that doesn't count ;->.
