I also added:

     We also add a backpointer to 'struct blkfront_info' (dev_info) which
    is not needed (we could use containers_of) but further patch
    ("xen/blkfront: pseudo support for multi hardware queues/rings")
    will make allocation of 'blkfront_ring_info' dynamic.

Fixed some odd tab spaces.

And put in my 'for-jens-4.5' branch.
