Subject: [PATCH] nvme: Translate more status codes to blk_status_t
Date: Fri,  6 Dec 2019 04:57:30 +0900	[thread overview]
Message-ID: <20191205195730.5774-1-kbusch@kernel.org> (raw)

Decode interrupted command and not ready namespace nvme status codes to
BLK_STS_TARGET. These are not generic IO errors and should use a non-path
specific error so that it can use the non-failover retry path.
