Subject: [PATCH] KVM: arm64: selftests: Allocate vcpus with correct size
Date: Wed, 8 Oct 2025 23:45:20 +0800 [thread overview]
Message-ID: <20251008154520.54801-1-zenghui.yu@linux.dev> (raw)
vcpus array contains pointers to struct kvm_vcpu {}. It is way overkill
to allocate the array with (nr_cpus * sizeof(struct kvm_vcpu)). Fix the
allocation by using the correct size.
