[PATCH 00/15] libnvdimm: ->rw_bytes(), BLK-mode, unit tests, and misc features

[Dan Williams <dan.j.williams@intel.com>]

This patchset takes the position that a new block_device_operations op
is needed for nvdimm devices.  Jens, see "[PATCH 01/15] block: introduce
an ->rw_bytes() block device operation", it gates the rest of the series
moving forward.

Aside from adding a compile-time check to tools/testing/nvdimm/Kbuild
for validating all libnvdimm objects are built as modules, patches 2 to
6 are otherwise unchanged from the v6 libnvdimm posting [1].  The
remaining patches are feature additions and other cleanups that were
being held back while the base patchset was polished.

Patch 5 has an updated changelog speaking to the potential maintenance
burden of carrying tools/testing/nvdimm/ in-tree.  The benefits still
outweigh the risks in my opinion.

It should be noted that "[PATCH 14/15] libnvdimm: support read-only btt
backing devices" was developed in direct repsonse to working through the
implementation of unit tests for "[PATCH 15/15] libnvdimm, nfit: handle
acpi_nfit_memory_map flags" and its new "read-only by default" policy.
See the updates to the libndctl unit tests posted on the
linux-nvdimm@01.org mailing list.
