tools/testing/nvdimm: dynamic label support
Update nfit_test infrastructure to enable labels for the dimm on the nfit_test.1 bus. This bus has a pmem region without aliased blk space, so it is a candidate for dynamically enabling label support by writing a namespace index block. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
