From 2dc3947b53f573e8a75ea9cbec5588df88ca502e Mon Sep 17 00:00:00 2001 From: Max Gurtovoy Date: Sun, 13 Oct 2019 19:57:35 +0300 Subject: nvme: introduce "Command Aborted By host" status code Fix the status code of canceled requests initiated by the host according to TP4028 (Status Code 0x371): "Command Aborted By host: The command was aborted as a result of host action (e.g., the host disconnected the Fabric connection)." Also in a multipath environment, unless otherwise specified, errors of this type (path related) should be retried using a different path, if one is available.
