Subject: [PATCH v9 01/14] KVM: Rename kvm_arch_flush_remote_tlb() to kvm_arch_flush_remote_tlbs()
Date: Fri, 11 Aug 2023 04:51:14 +0000	[thread overview]
Message-ID: <20230811045127.3308641-2-rananta@google.com> (raw)
In-Reply-To: <20230811045127.3308641-1-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.
