Merge branch 'for-4.8/block' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm into for-4.8/drivers 

Dan writes:

"The removal of ->driverfs_dev in favor of just passing the parent
device in as a parameter to add_disk().  See below, it has received a
"Reviewed-by" from Christoph, Bart, and Johannes.

It is also a pre-requisite for Fam Zheng's work to cleanup gendisk
uevents vs attribute visibility [1].  We would extend device_add_disk()
to take an attribute_group list.

This is based off a branch of block.git/for-4.8/drivers and has
received a positive build success notification from the kbuild robot
across several configs.

[1]: "gendisk: Generate uevent after attribute available"
