From 2b2d85125ed8ae67e43bdc9cdb808a8d9ec5ac2f Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 2 Sep 2021 10:59:51 -0700 Subject: [PATCH] KVM: Remove unnecessary export of kvm_{inc,dec}_notifier_count() Don't export KVM's MMU notifier count helpers, under no circumstance should any downstream module, including x86's vendor code, have a legitimate reason to piggyback KVM's MMU notifier logic. E.g in the x86 case, only KVM's MMU should be elevating the notifier count, and that code is always built into the core kvm.ko module.
