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.
