From 0046b06a367cd853efd3223ce60143f3a7952522 Mon Sep 17 00:00:00 2001 From: Willem Riede Date: Wed, 9 Nov 2005 23:18:22 +0100 Subject: [PATCH] [PATCH] ide: ide-scsi fails to call idescsi_check_condition for things like "Medium not present" This patch started life as a response to fedora specific ide subsystem changes that made error handling of my ATAPI tape drive fail; the specifics are in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160868 The insertion of the statement rq->errors = err; near the end of ide_end_drive_cmd() in drivers/ide/ide-io.c means that rq->errors does not contain what it needs to in idescsi_end_request() in drivers/scsi/ide-scsi.c anymore. Recent mainline kernels now also have this change. The patch below makes ide-scsi whole.
