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@xxxxxx mailing list.
