Hmm, looking at the original report referenced, my patches need not fix this
particular warning. This particular warning rather looks like a race when
udisks-part-id manages to read the device (and touch it's atime) before
sd_probe_async runs and registers the bdi (via add_disk()). That seems to be
possible as device_add() is run before we even schedule to run sd_async_probe()
in a separate thread.

Jens, any idea how this should be fixed? I believe we should avoid this race
because we should better have the device's queue fully set up before allowing
IO to it... But I'm far from fully understanding this area...
