You'd basically just be pulling my tree (Christoph's is just my nfsd
tree with his patches on top, and I've been testing with exactly that
locally, just putting off pushing it out till we decide this.)

So anyway, fine with me if you want to just pull that into the xfs tree.
Mine's ready whenever, so if I send my pull pretty soon after the merge
window and you send it a little later then we still keep the property
that Linus's merge still has a diffstat only in our respective areas.

(OK, it's a little more complicated because I've got the same
arrangement with jlayton, so the order is jlayton's lock pull, then my
nfsd pull, then your xfs pull.  Is this getting too complicated?
jlayton and I are both ready to so and I think it'd work.)

I'm also fine with duplicating those few patches, or whatever.
