From c9b851905dba3a688dd75970df02305518f9554a Mon Sep 17 00:00:00 2001 From: Peter Oberparleiter Date: Tue, 26 Nov 2013 15:00:37 +0100 Subject: [PATCH] s390/blacklist: Perform subchannel scan only when needed Move scheduling of a subchannel scan to those instances where new devices may actually have become available. This reduces unnecessary scan work in case devices were added to the blacklist.
