Well, in the absence of further information and being unaware of any
other driver doing this, rather than changing several places in the
block layer to cope with one out-of-the-ordinary driver, I wish to see
the driver fixed to work within the existing block layer design.  If
that is difficult or impossible (which I doubt), then we need more
information to justify that position.

Meanwhile I will not be applying that patch, though I may take a patch
to provide clean diagnostics should a situation like this occur again.
