Subject: [PATCH 1/6] nfit/ars: Attempt a short-ARS whenever the ARS state is idle at boot
Date: Thu, 14 Feb 2019 12:10:10 -0800 [thread overview]
Message-ID: <155017501057.944049.2284804890743224154.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

If query-ARS reports that ARS has stopped and requires continuation
attempt to retrieve short-ARS results before continuing the long
operation.
