From cbc0236a4b3e6a64f5b8bee27b530c7f8bee8d56 Mon Sep 17 00:00:00 2001 From: Roman Kagan Date: Thu, 1 Feb 2018 16:48:31 +0300 Subject: [PATCH] kvm: x86: factor out kvm.arch.hyperv (de)init MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Move kvm.arch.hyperv initialization and cleanup to separate functions. For now only a mutex is inited in the former, and the latter is empty; more stuff will go in there in a followup patch.
