bdev_get_integrity() and bdev_get_tag_size() are being used by
stacking drivers and filesystems to prepare I/O.  It's correct that
none of the in-tree stuff currently uses bdev_get_tag_size().  That's
coming with the btrfs support.  If you want to pull that out for now
and have me put that back later in that's ok.  Just adds another
two-stage merge dependency for a later cycle.

bdev_integrity_enabled() and blk_integrity_tuple_size() are only being
used from within bio-integrity.c and can move there.  I originally put
them in blkdev.h because they are block device functions and not bio
ditto.

Want me to submit a new patch shuffling bdev_get_integrity() back
where it came from?
