Hi Jens,

this series switches back from storing the gendisk + partno to storing
a block_device pointer in struct bio.  The reason is two fold:  for one
the new struct block_device actually is always available, removing the
need to avoid originally.  Second the merge struct block_device is much
more useful than the old one, as storing it avoids the need for looking
up what used to be hd_struct during partition remapping and I/O
accounting.

Applied for 5.12, thanks.
