Message-ID: <20150711144053.25013.48187.stgit@dwillia2-desk3.amr.corp.intel.com> Date: Sat, 11 Jul 2015 10:40:53 -0400 From: Dan Williams <dan.j.williams@...el.com> To: linux-nvdimm@...ts.01.org Cc: linux-acpi@...r.kernel.org, ross.zwisler@...ux.intel.com, linux-kernel@...r.kernel.org Subject: [PATCH v2 3/6] tools/testing/nvdimm: fix return code for unimplemented commands The implementation for the new "DIMM Flags" DSM relies on the -ENOTTY return code to indicate that the flags are unimplimented and to fall back to a safe default. As is the -ENXIO error code erroneoously indicates to fail enabling a BLK region.
