Subject: [PATCH] fixup! KVM: s390 allow virtio_ccw status writes to fail
Date: Thu, 23 Oct 2014 20:49:18 +0300 [thread overview]
Message-ID: <1414086476-24772-1-git-send-email-mst@redhat.com> (raw)
Forgot that I need a cross-compiler for s390 changes, so of course
they don't build :(
Will repost later, for now here's a fix.
