For magic prefixes we use __, not _ in Linux. But having two arrays
of queues right next to each other, once with rcu annotation and one
not rings a bit far warning bell to me. Why do we have both? When
are we supposed to use either? Why is FC different from rest?

I really don't have any good answers as I don't know the code in the
FC transport very well, but I think this needs more work.
