4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Williams <dan.j.williams@intel.com>
commit 3fa58dcab50a0aa16817f16a8d38aee869eb3fb9 upstream.
When the platform BIOS is unable to report all the media error records it requires the OS to restart the scrub at a prescribed location. The driver detects the overflow condition, but then fails to report it to the ARS state machine after reaping the records. Propagate -ENOSPC correctly to continue the ARS operation.
