Subject: [PATCH 0/3] Introduce device_add_disk() to kill gendisk.driverfs_dev

Answer the "// FIXME: remove" include/linux/genhd.h.  This should be
functionally equivalent to the previous state.  Now that the WARN_ON()
for the registration failure case is up-levelled to some drivers, they
can take on the follow on work to handle device_add_disk() failures.

Note, a full run from the kbuild robot is still pending.  I'll post v2
if it reports anything against this set on top of current -next.
