From 1fbdb8be9bfc91efd45720493c7ecae884ae22bd Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Wed, 30 Jan 2013 09:26:13 +0000 Subject: [PATCH] s390/dasd: process all requests in the device tasklet Originally the DASD device tasklet would process the entries on the ccw_queue until the first non-final request was found. Which was okay as long as all requests have the same retries and expires parameter. However, as we're now allowing to modify both it is possible to have requests _after_ the first request which already have expired. So we need to check all requests in the device tasklet.
