Hi Dave, Thanks for the clarification. Yes now I am able to get your point clear.

I should split this patch into two patches
1. First prep patch with no functionality change (Just code movement from core/region.c to newly core/pmem_region.c)
2. Second patch which calls the libnvdimm exported routines
	- region_label_update_show/store()
	- region_label_delete_store()

Regards,
Neeraj
