Message-Id: <1266316536-28936-22-git-send-email-avi@redhat.com> Date: Tue, 16 Feb 2010 12:35:19 +0200 From: Avi Kivity <avi@...hat.com> To: kvm@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 21/38] KVM: MMU: Remove some useless code from alloc_mmu_pages() From: Wei Yongjun <yjwei@...fujitsu.com> If we fail to alloc page for vcpu->arch.mmu.pae_root, call to free_mmu_pages() is unnecessary, which just do free the page malloc for vcpu->arch.mmu.pae_root.
