Subject: [PATCH v2 02/22] KVM: arm64: Remove kvm_mmu_free_memory_caches()
Date: Tue, 18 Aug 2020 14:27:58 +0100 [thread overview]
Message-ID: <20200818132818.16065-3-will@kernel.org> (raw)
In-Reply-To: <20200818132818.16065-1-will@kernel.org>
kvm_mmu_free_memory_caches() is only called by kvm_arch_vcpu_destroy(),
so inline the implementation and get rid of the extra function.
