Subject: [PATCH] nvme: Translate more status codes to blk_status_t
Patch-Mainline: v5.5-rc6
Git-commit: 35038bffa87da282010b91108cadd13238bb5bbd
References: bsc#1156510
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.
