Hi Geliang, kernel test robot noticed the following build warnings: [auto build test WARNING on bpf-next/master] url: https://github.com/intel-lab-lkp/linux/commits/Geliang-Tang/bpf-Add-update_socket_protocol-hook/20230803-153209 base: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git master patch link: https://lore.kernel.org/r/120b307aacd1791fac016d33e112069ffb7db21a.1691047403.git.geliang.tang%40suse.com patch subject: [PATCH bpf-next v8 1/4] bpf: Add update_socket_protocol hook config: nios2-randconfig-r006-20230731 (https://download.01.org/0day-ci/archive/20230803/202308032054.aq4D9VOg-lkp@xxxxxxxxx/config) compiler: nios2-linux-gcc (GCC) 12.3.0 reproduce: (https://download.01.org/0day-ci/archive/20230803/202308032054.aq4D9VOg-lkp@xxxxxxxxx/reproduce) If you fix the issue in a separate patch/commit (i.e. not just a new version of the same patch/commit), kindly add following tags | Reported-by: kernel test robot <lkp@xxxxxxxxx> | Closes: https://lore.kernel.org/oe-kbuild-all/202308032054.aq4D9VOg-lkp@xxxxxxxxx/ All warnings (new ones prefixed by >>): >> net/socket.c:1648: warning: This comment starts with '/**', but isn't a kernel-doc comment.
