From b34cb590fb099f7929dd78d9464b70319ee12a98 Mon Sep 17 00:00:00 2001 From: Takuya Yoshikawa Date: Tue, 8 Jan 2013 19:46:07 +0900 Subject: [PATCH] KVM: Make kvm_mmu_change_mmu_pages() take mmu_lock by itself No reason to make callers take mmu_lock since we do not need to protect kvm_mmu_change_mmu_pages() and kvm_mmu_slot_remove_write_access() together by mmu_lock in kvm_arch_commit_memory_region(): the former calls kvm_mmu_commit_zap_page() and flushes TLBs by itself. Note: we do not need to protect kvm->arch.n_requested_mmu_pages by mmu_lock as can be seen from the fact that it is read locklessly.
