Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dan Williams:
"A fix and regression test case for nvdimm namespace label
compatibility.
Details:
- An "nvdimm namespace label" is metadata on an nvdimm that
provisions dimm capacity into a "namespace" that can host a block
device / dax-filesytem, or a device-dax character device.
A namespace is an object that other operating environment and
platform firmware needs to comprehend for capabilities like booting
from an nvdimm.
The label metadata contains a checksum that Linux was not
calculating correctly leading to other environments rejecting the
Linux label.
These have received a build success notification from the kbuild
robot, and a positive test result from Nick who reported the problem"
