What about the reverse?  If the user specifies the backing device,
don't we need to canonicalize it to the /dev/md/ path?

In other words, the problem is not canonicalizing the device, it's
*how* it is canonicalized.  Rather than just following the symlink, or
using the user argument unmodified, we need to ask the kernel what the
device's canonical ( /dev/md/ ) name is and use that.
