Message-ID: <20240821112737.3649937-1-liuyongqiang13@huawei.com> Date: Wed, 21 Aug 2024 19:27:37 +0800 From: Yongqiang Liu <liuyongqiang13@...wei.com> To: <kvm@...r.kernel.org> CC: <linux-kernel@...r.kernel.org>, <zhangxiaoxu5@...wei.com>, <hpa@...or.com>, <x86@...nel.org>, <dave.hansen@...ux.intel.com>, <bp@...en8.de>, <mingo@...hat.com>, <tglx@...utronix.de>, <pbonzini@...hat.com>, <seanjc@...gle.com>, <liuyongqiang13@...wei.com> Subject: [PATCH -next] KVM: SVM: Remove unnecessary GFP_KERNEL_ACCOUNT in svm_set_nested_state() The fixed size temporary variables vmcb_control_area and vmcb_save_area allocated in svm_set_nested_state() are released when the function exits. Meanwhile, svm_set_nested_state() also have vcpu mutex held to avoid massive concurrency allocation, so we don't need to set GFP_KERNEL_ACCOUNT.
