From a2ace46632fb38c7a3771f2f0d235a4295e83bcf Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Wed, 30 Jan 2013 09:26:14 +0000 Subject: s390/dasd: Implement block timeout handling This patch implements generic block layer timeout handling callbacks for DASDs. When the timeout expires the respective cqr is aborted. With this timeout handler time-critical request abort is guaranteed as the abort does not depend on the internal state of the various DASD driver queues.
