Subject: Re: [PATCH 3/4] KVM: nSVM: implement check_nested_events for
interrupts
Hi Paolo,
I love your patch! Yet something to improve:
[auto build test ERROR on kvm/linux-next]
[also build test ERROR on linus/master v5.6-rc4 next-20200305]
[cannot apply to linux/master vhost/linux-next]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
url: https://github.com/0day-ci/linux/commits/Paolo-Bonzini/KVM-nSVM-first-step-towards-fixing-event-injection/20200306-015933
base: https://git.kernel.org/pub/scm/virt/kvm/kvm.git linux-next
config: x86_64-rhel (attached as .config)
compiler: gcc-7 (Debian 7.5.0-5) 7.5.0
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64
If you fix the issue, kindly add following tag
