Subject: [PATCH] kvm: svm: de-allocate svm_cpu_data for all cpus in svm_cpu_uninit()
Date: Thu, 3 Dec 2020 12:59:39 -0800 [thread overview]
Message-ID: <20201203205939.1783969-1-jacobhxu@google.com> (raw)
The cpu arg for svm_cpu_uninit() was previously ignored resulting in the
per cpu structure svm_cpu_data not being de-allocated for all cpus.
