I still don't understand *why* you play the crazy VM games to begin with.

What's wrong with just returning SIGBUS? Why does that
rdma_umap_fault() not just look like this one-liner:

        return VM_FAULT_SIGBUS;

without the crazy parts? Nobody ever explained why you'd want to have
that silly "let's turn it into a bogus anonymous mapping".

I've pulled this, but why do the rdma and SCSI people always do these
strange and pointless things?
