[PATCH v5 0/5] Introduce device_add_disk() to kill gendisk.driverfs_dev

[Dan Williams]

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.
