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" http://marc.info/?l=linux-virtualization&m=146725201522201&w=2"
