From 59f68474c2a1f5f0cedede60b60de97c603dc194 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 25 Apr 2016 12:45:50 +0200 Subject: [PATCH] libata-scsi: Generate sense code for disabled devices If a device is disabled after error recovery it doesn't make any sense to generate an ATA sense, but we should rather return a generic sense code indicating the device is gone.
