At initialization time the 'dimm' driver caches a copy of the memory
device's label area and reserves address space for each of the
namespaces defined.
However, as can be seen below, the reservation occurs even when the
index blocks are invalid:
nvdimm nmem0: nvdimm_init_config_data: len: 131072 rc: 0
nvdimm nmem0: config data size: 131072
nvdimm nmem0: __nd_label_validate: nsindex0 labelsize 1 invalid
nvdimm nmem0: __nd_label_validate: nsindex1 labelsize 1 invalid
nvdimm nmem0: : pmem-6025e505: 0x1000000000 @ 0xf50000000 reserve <-- bad
Gate dpa reservation on the presence of valid index blocks.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
