Scratch that. I got it. It is the lockdep annotation which I got wrong
with my patch. I thought this was done much later in the slow path.
My head is burnt so I will get back to it tomorrow. The patch 1.1 should
be OK to go for XFS though because it doesn't really introduce anything
new.

Sorry about the noise!
