Subject: [PATCH 1/4] KVM: constify kvm_arch_flush_remote_tlbs_memslot
Date: Fri, 2 Apr 2021 17:58:04 +0200 [thread overview]
Message-ID: <20210402155807.49976-2-pbonzini@redhat.com> (raw)
In-Reply-To: <20210402155807.49976-1-pbonzini@redhat.com>
memslots are stored in RCU and there should be no need to
change them.
