Subject: [PATCH 09/14] libnvdimm, namespace: expand pmem device naming scheme for multi-pmem
Date: Fri, 07 Oct 2016 09:39:29 -0700	[thread overview]
Message-ID: <147585836894.22349.11287745776727706515.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <147585832067.22349.6376523541984122050.stgit@dwillia2-desk3.amr.corp.intel.com>

pmem devices are currently named /dev/pmem<region-index>. Preserve the
naming of the 0th device, but add a ".<namespace-index>" for other
devices.
