Please pull to receive libnvdimm contributions for v4.19-rc1. I have separated out the topic branches and
will be sending pull requests for them individually.
This branch contains all the original patches from the first pull request without the dax-memory-failure series.

The following changes since commit 1273c253c32b9a073a4d8921ed079177ccc7c8af:

  tools/testing/nvdimm: advertise a write cache for nfit_test (2018-06-30 10:45:48 -0700)
