From 3d11df7abbff013b811d5615320580cd5d9d7d31 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Thu, 27 Sep 2012 17:29:45 +0200 Subject: KVM: s390: Fix vcpu_load handling in interrupt code Recent changes (KVM: make processes waiting on vcpu mutex killable) now requires to check the return value of vcpu_load. This triggered a warning in s390 specific kvm code. Turns out that we can actually remove the put/load, since schedule will do the right thing via the preempt notifiers.
