Hi Mathieu, [FYI, it's a private test report for your RFC patch.] [auto build test WARNING on tip/x86/asm] [also build test WARNING on tip/sched/core] [cannot apply to linus/master linux/master v5.8-rc1 next-20200616] [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/Mathieu-Desnoyers/sched_pair_cpu... base: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git 2ce0d7f9766f0e49bb54f149c77bae89464932fb config: nds32-randconfig-c023-20200615 (attached as .config) compiler: nds32le-linux-gcc (GCC) 9.3.0 If you fix the issue, kindly add following tag as appropriate Reported-by: kernel test robot <lkp(a)intel.com&gt; All warnings (new ones prefixed by >>, old ones prefixed by <<): In file included from include/linux/kernel.h:11, from include/linux/list.h:9, from include/linux/rculist.h:10, from include/linux/pid.h:5, from include/linux/sched.h:14, from arch/nds32/kernel/asm-offsets.c:4: include/linux/sched.h: In function 'sched_pair_cpu_set_notify_resume': include/linux/sched.h:1913:13: error: 'struct task_struct' has no member named 'pair_cpu' 1913 | if (current->pair_cpu >= 0) | ^~ include/linux/compiler.h:58:52: note: in definition of macro '__trace_if_var' 58 | #define __trace_if_var(cond) (__builtin_constant_p(cond) ?
