I may be mistaken, but from my (brief) reading of the code it seems to
me that perhaps "swap-backed" isn't an entirely accurate term.  More
like "VM-backed", with the understanding that VM is (usually) backed by
swap.

I think if you don't have any swap configured, a swap-backed md will be
no worse off than a memory-backed one would.
