From 024c3c3304ca36c23ee400b507fb59ae2e2db7fa Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Sun, 5 Jun 2022 14:34:16 +0800 Subject: [PATCH] KVM: X86/MMU: Remove useless mmu_topup_memory_caches() in kvm_mmu_pte_write() Since the commit c5e2184d1544("KVM: x86/mmu: Remove the defunct update_pte() paging hook"), kvm_mmu_pte_write() no longer uses the rmap cache. So remove mmu_topup_memory_caches() in it.
