The v3 patch doesn't have "Signed-off-by". You can see all the checks on patchwork: https://patchwork.kernel.org/project/netdevbpf/patch/20201213204339.24445-2-v@nametag.social/ For patches to netdev, please include the target. Here it should be net-next: https://www.kernel.org/doc/Documentation/networking/netdev-FAQ.txt git format-patch --subject-prefix='PATCH net-next v4' ... Also, since this patch affects udp, it's preferred to include "udp: " in your commit's subject line. In other words, the v4 of this patch should look like the following: [PATCH net-next v2] udp: allow UDP cmsghdrs through io_uring Thank you > GSO and GRO are vital to bring QUIC servers on par with TCP throughputs, and together offer a higher > throughput gain than io_uring alone (rate of data transit > considering), thus io_uring is presently the lesser performance choice. > > RE http://vger.kernel.org/lpc_net2018_talks/willemdebruijn-lpc2018-udpgso-paper-DRAFT-1.pdf, > GSO is about +~63% and GRO +~82%. > > this patch closes that loophole. > > net/ipv4/af_inet.c | 1 + > net/ipv6/af_inet6.c | 1 + > net/socket.c | 8 +++++--- > 3 files changed, 7 insertions(+), 3 deletions(-) > >
