From 7ddca7e43c8f28f9419da81a0e7730b66aa60fe9 Mon Sep 17 00:00:00 2001 From: Takuya Yoshikawa Date: Thu, 21 Mar 2013 19:33:43 +0900 Subject: [PATCH] KVM: MMU: Move kvm_mmu_free_some_pages() into kvm_mmu_alloc_page() What this function is doing is to ensure that the number of shadow pages does not exceed the maximum limit stored in n_max_mmu_pages: so this is placed at every code path that can reach kvm_mmu_alloc_page(). Although it might have some sense to spread this function in each such code path when it could be called before taking mmu_lock, the rule was changed not to do so. Taking this background into account, this patch moves it into kvm_mmu_alloc_page() and simplifies the code. Note: the unlikely hint in kvm_mmu_free_some_pages() guarantees that the overhead of this function is almost zero except when we actually need to allocate some shadow pages, so we do not need to care about calling it multiple times in one path by doing kvm_mmu_get_page() a few times.
