From ff520a6327e83ef55515d1be3d0a1b10c084f59c Mon Sep 17 00:00:00 2001 From: Jens Freimann Date: Mon, 24 Feb 2014 10:11:41 +0100 Subject: [PATCH] KVM: s390: Simplify online vcpus counting for stsi We don't need to loop over all cpus to get the number of vcpus. Let's use the available counter online_vcpus instead.
