I think we should move this new functionality to the core because
there is not much pmem driver specific. It's all generic nvdimm-core
and block-core functionality. The only missing information the core
routine needs is the gendisk and a data offset (if sector-zero is at
an offset from the base address range of the namespace). Something
like:
nvdimm_namespace_disk_poison(struct nd_namespace_common *ndns,
resource_size_t offset, struct gendisk *disk)
