From a1342c8027288e345cc5fd16c6800f9d4eb788ed Mon Sep 17 00:00:00 2001 From: David Matlack Date: Fri, 11 Aug 2023 04:51:14 +0000 Subject: KVM: Rename kvm_arch_flush_remote_tlb() to kvm_arch_flush_remote_tlbs() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rename kvm_arch_flush_remote_tlb() and the associated macro __KVM_HAVE_ARCH_FLUSH_REMOTE_TLB to kvm_arch_flush_remote_tlbs() and __KVM_HAVE_ARCH_FLUSH_REMOTE_TLBS respectively. Making the name plural matches kvm_flush_remote_tlbs() and makes it more clear that this function can affect more than one remote TLB. No functional change intended.
