From eb7fd4d0f64fcab2da9ae454a1f214174e881372 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Tue, 19 Jun 2018 15:41:39 +0200 Subject: nvdimm: convert nvdimm_mr into a pointer This way we can easily check if the region has already been inititalized without having to rely on the size of an uninitialized region being 0. Free the region in nvdimm_finalize() and not in unrealize() as we will allow to create the region before realization in following patches.
