I am still trying to get Arla to work after the ktrace-lwp merge. One
thing I noticed is that it has a nnpfs_uio_to_proc() macro.
How would situations like this be dealt with?

It would be nice if we could import Arla so that adjusting it for all
these API changes could be the responsibility of the person making the
change, who presumably knows how things are supposed to work afterwards,
instead of me, who has to figure it out every couple months :-)
