Message-Id: <1449038369-752-1-git-send-email-krivenok.dmitry@gmail.com> Date: Wed, 2 Dec 2015 09:39:29 +0300 From: "Dmitry V. Krivenok" <krivenok.dmitry@...il.com> To: Dan Williams <dan.j.williams@...el.com> Cc: linux-nvdimm@...ts.01.org, linux-kernel@...r.kernel.org, Ross Zwisler <ross.zwisler@...ux.intel.com>, "Dmitry V. Krivenok" <krivenok.dmitry@...il.com> Subject: [PATCH] nvdimm: do not show pfn_seed for non pmem regions This simple change hides pfn_seed attribute for non pmem regions because they don't support pfn anyway.
