Subject: [PATCH 3/6] KVM: s390: fix sigp sense running condition code handling
Date: Tue, 26 Jun 2012 16:06:38 +0200 [thread overview]
Message-ID: <1340719601-11867-4-git-send-email-cornelia.huck@de.ibm.com> (raw)
In-Reply-To: <1340719601-11867-1-git-send-email-cornelia.huck@de.ibm.com>
From: Heiko Carstens <heiko.carstens@de.ibm.com>
Only if the sensed cpu is not running a status is stored, which
is reflected by condition code 1. If the cpu is running, condition
code 0 should be returned.
Just the opposite of what the code is doing.
