Done. I've also done more performance testing, and it seems that now
it would be a win again to do the "prefetch inode" in
__d_lookup_rcu().

But I'll leave it be for now. My test loads are ridiculously
pathname-intensive, I don't know if anything else really cares that
deeply.

At least there is no longer anything in the profiles that look
horribly stupid (except for the security subsystem - pointer chasing
through i_security, and I can't see anything we can do about that).
