Merge branch 'for-5.1/nfit/ars' into libnvdimm-for-next
Merge several updates to the ARS implementation. Highlights include: * Support retrieval of short-ARS results if the ARS state is "requires continuation", and even if the "no_init_ars" module parameter is specified. * Allow busy-polling of the kernel ARS state by allowing root to reset the exponential back-off timer. * Filter potentially stale ARS results by tracking query-ARS relative to the previous start-ARS.
