Subject: Re: [PATCH v1 2/2] arm/arm64: KVM: Add KVM_GET/SET_VCPU_EVENTS
Hi Dongjiu,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on arm64/for-next/core]
[also build test ERROR on v4.17 next-20180601]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
