Subject: [RESEND PATCH v5 01/11] KVM: Rename kvm_arch_flush_remote_tlb() to kvm_arch_flush_remote_tlbs()
Date: Wed, 21 Jun 2023 17:49:52 +0000 [thread overview]
Message-ID: <20230621175002.2832640-2-rananta@google.com> (raw)
In-Reply-To: <20230621175002.2832640-1-rananta@google.com>
From: David Matlack <dmatlack@google.com>
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.
