From 0e3b0d123c8fd5c42f364aea3ab663b1f18dad39 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 6 Oct 2016 23:13:15 -0700 Subject: libnvdimm, namespace: allow multiple pmem-namespaces per region at scan time If label scanning finds multiple valid pmem namespaces allow them to be surfaced rather than fail namespace scanning. Support for creating multiple namespaces per region is saved for a later patch. Note that this adds some new error messages to clarify which of the pmem namespaces in the set are potentially impacted by invalid labels.
