Subject: [PATCH v4 15/26] KVM: kvm_arch.c: Remove _nolock post fix
Date:   Thu,  8 Sep 2022 16:25:31 -0700
Message-Id: <c3f1840c3e41a4496de14ae22b8a9bce79dc7a53.1662679124.git.isaku.yamahata@intel.com>

From: Isaku Yamahata <isaku.yamahata@intel.com>

Now all related callbacks are called under kvm_lock, no point for _nolock
post fix.  Remove _nolock post fix for readability with shorter function
names.
