Subject: [PATCH AUTOSEL 4.14 6/9] s390/dasd: use correct number of retries for ERP requests
Date: Sun, 13 Aug 2023 12:14:24 -0400	[thread overview]
Message-ID: <20230813161427.1089101-6-sashal@kernel.org> (raw)
In-Reply-To: <20230813161427.1089101-1-sashal@kernel.org>

From: Stefan Haberland <sth@linux.ibm.com>

[ Upstream commit acea28a6b74f458defda7417d2217b051ba7d444 ]

If a DASD request fails an error recovery procedure (ERP) request might
be built as a copy of the original request to do error recovery.

The ERP request gets a number of retries assigned.
This number is always 256 no matter what other value might have been set
for the original request. This is not what is expected when a user
specifies a certain amount of retries for the device via sysfs.

Correctly use the number of retries of the original request for ERP
requests.
