Subject: [PATCH] accel/kvm/kvm-all: Fixes the missing break in vCPU unpark logic
Date: Thu, 25 Jul 2024 15:51:32 +0100	[thread overview]
Message-ID: <20240725145132.99355-1-salil.mehta@huawei.com> (raw)

Loop should exit prematurely on successfully finding out the parked vCPU (struct
KVMParkedVcpu) in the 'struct KVMState' maintained 'kvm_parked_vcpus' list of
parked vCPUs.

Fixes: Coverity CID 1558552
Fixes: 08c3286822 ("accel/kvm: Extract common KVM vCPU {creation,parking} code")
Reported-by: Peter Maydell <peter.maydell@linaro.org>
Suggested-by: Peter Maydell <peter.maydell@linaro.org>
