Actually it came in with revision 228889 in 2009. The script at
that point didn't allow for tmpfs and only checks for an existing md
device before creating a malloc md device (i.e. in unswapable wired
kernel memory).  IIRC there used to be a warning about this kind of md
device being able to cause crashes.
