Changes since v4 [1]:
1/ Continue to populate ->driverfs_dev until the final removal so that
there are no behavior changes in the middle of the series, for example
in printk_all_partitions(). (Bart)
2/ Use more descriptive 'parent' variable name instead of 'dev' in
ubd_kern.c to indicate the parent device (Bart).
3/ Remove Reported-by tags per Bart's request.

Answer the "// FIXME: remove" include/linux/genhd.h. This should be
functionally equivalent to the previous state. These patches received a
build success notification from the kbuild robot.

In preparation for removing the ->driverfs_dev member of a gendisk, add
an api that takes the parent device as a parameter to add_disk(). For
now this maintains the status quo of WARN()ing on failure, but not
return a error code.

For block drivers that specify a parent device, convert them to use
device_add_disk().
This conversion was done with the following semantic patch:
@@
struct gendisk *disk;
expression E;

- disk->driverfs_dev = E;
