Subject: Re: [RFC PATCH 6/7] selftest: tun: Add tests for virtio-net hashing
hi, Akihiko Odaki,
sorry for sending again, the previous one has some problem that lost most
of CC part.
Hello,
kernel test robot noticed "kernel-selftests.net.make.fail" on:
commit: c04079dfb34c2f534f013408b12218c14b286b7d ("[RFC PATCH 6/7] selftest: tun: Add tests for virtio-net hashing")
url: https://github.com/intel-lab-lkp/linux/commits/Akihiko-Odaki/net-skbuff-Add-tun_vnet_hash-flag/20231008-133245
base: https://git.kernel.org/cgit/linux/kernel/git/shuah/linux-kselftest.git next
patch link: https://lore.kernel.org/all/20231008052101.144422-7-akihiko.odaki@daynix.com/
