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.
