nvme: introduce "Command Aborted By host" status code (2dc3947b) · Commits · 戴 / test

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. Signed-off-by:
