From 9d04edd23e6ab368d25ca0adde6f1676185d49f8 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 26 Jun 2012 16:06:36 +0200 Subject: [PATCH] s390/smp: remove redundant check condition code "status stored" for sigp sense running always implies that only the "not running" status bit is set. Therefore no need to check if it is set.
