Subject: Re: [PATCH v3 3/7] x86/hyper-v: reenlightenment notifications support
Hi Vitaly,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on tip/auto-latest]
[also build test WARNING on v4.15-rc8 next-20180118]
[cannot apply to tip/x86/core kvm/linux-next]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
