I'm in favour of deprecating it.  Whenever I hear of people using it I
suggest dm-multipath, but there could people I don't here about.
I think the upcoming mdadm-3.0 will need a compile-time option to
enable multipath, so people will only get it if they really really
want it.

So feel free to propose patches.

Thanks :-)
