Subject: [PATCH 6/7] s390/dasd: add autoquiesce event for start IO error
Date: Wed, 5 Apr 2023 16:20:16 +0200 [thread overview]
Message-ID: <20230405142017.2446986-7-sth@linux.ibm.com> (raw)
In-Reply-To: <20230405142017.2446986-1-sth@linux.ibm.com>
Add a check for errors in the start_io function that signal a not
working device. Trigger an autoquiesce event in that case.
