The tricky part here is that our tree also has kdb in it, if you
subtract out kdb then it gets a lot easier in general to apply
xfs to other random kernels. Although when it comes to vm changes
we have code in buffer.c and vmscan.c which it is essential to
get right.

kdb patches which you can fairly cleanly reverse apply to an xfs
tree are available from oss.sgi.com in projects/kdb.
