in that ktrace output, mmap() doesn't fail anywhere, which would have been
the effect of the kernfs change that I made.

the only reference to /kern at all is that xend opens /kern/xen/privcmd,
but as far as I can tell it doesn't do anything with that file descriptor.

I don't see how this is related to the kernfs change.
