I have a question on the default REGION creation (unlabeled NVDIMM) on the Interleave Sets. I observe that for a Single Interleave Set, the Linux Kernels earlier to 4.9 create only one "Region0->namespace0.0" (pmem0 for the entire size), but in the later Kernels I observe for the same Interleave Set it creates "Region0->namespace0.0" and "Region1->namespace1.0" by default (pmem0, pmem1 for half the size of the Interleave set).
I don't have any explicit labels created using the ndctl utilities. I just plug-in the fresh NVDIMM modules like I always do. I searched for and found the relevant information on that front regarding the nd_pmem driver and the support for multiple pmem namespaces. I am wondering whether is there a way I could -- through Kernel Parameters or something -- get the default behavior the same as it existed before Kernel 4.9 driver changes.
