 "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
