Hi Masami, I love your patch! Yet something to improve: [auto build test ERROR on trace/for-next] [also build test ERROR on lwn/docs-next linus/master v5.5-rc3] [cannot apply to tip/perf/core next-20191220] [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/Masami-Hiramatsu/tracing-bootconfig-Boot-time-tracing-and-Extra-boot-config/20191227-002009 base: https://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git for-next config: xtensa-allyesconfig (attached as .config) compiler: xtensa-linux-gcc (GCC) 7.5.0 reproduce: wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # save the attached .config to linux build tree GCC_VERSION=7.5.0 make.cross ARCH=xtensa If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All error/warnings (new ones prefixed by >>): In file included from kernel/trace/trace_boot.c:9:0: >> include/linux/ftrace.h:719:50: error: expected identifier or '(' before '{' token #define ftrace_set_filter(ops, buf, len, reset) ({ -ENODEV; }) ^ >> kernel/trace/trace_boot.c:249:12: note: in expansion of macro 'ftrace_set_filter' extern int ftrace_set_filter(struct ftrace_ops *ops, unsigned char *buf, ^~~~~~~~~~~~~~~~~ include/linux/ftrace.h:720:51: error: expected identifier or '(' before '{' token #define ftrace_set_notrace(ops, buf, len, reset) ({ -ENODEV; }) ^ >> kernel/trace/trace_boot.c:251:12: note: in expansion of macro 'ftrace_set_notrace' extern int ftrace_set_notrace(struct ftrace_ops *ops, unsigned char *buf, ^~~~~~~~~~~~~~~~~~ -- In file included from kernel//trace/trace_boot.c:9:0: >> include/linux/ftrace.h:719:50: error: expected identifier or '(' before '{' token #define ftrace_set_filter(ops, buf, len, reset) ({ -ENODEV; }) ^ kernel//trace/trace_boot.c:249:12: note: in expansion of macro 'ftrace_set_filter' extern int ftrace_set_filter(struct ftrace_ops *ops, unsigned char *buf, ^~~~~~~~~~~~~~~~~ include/linux/ftrace.h:720:51: error: expected identifier or '(' before '{' token #define ftrace_set_notrace(ops, buf, len, reset) ({ -ENODEV; }) ^ kernel//trace/trace_boot.c:251:12: note: in expansion of macro 'ftrace_set_notrace' extern int ftrace_set_notrace(struct ftrace_ops *ops, unsigned char *buf, ^~~~~~~~~~~~~~~~~~ vim +/ftrace_set_filter +249 kernel/trace/trace_boot.c 246 247 #ifdef CONFIG_FUNCTION_TRACER 248 extern bool ftrace_filter_param __initdata; > 249 extern int ftrace_set_filter(struct ftrace_ops *ops, unsigned char *buf, 250 int len, int reset); > 251 extern int ftrace_set_notrace(struct ftrace_ops *ops, unsigned char *buf, 252 int len, int reset); 253 static void __init 254 trace_boot_set_ftrace_filter(struct trace_array *tr, struct xbc_node *node) 255 { 256 struct xbc_node *anode; 257 const char *p; 258 char *q; 259 260 xbc_node_for_each_array_value(node, "ftrace.filters", anode, p) { 261 q = kstrdup(p, GFP_KERNEL); 262 if (!q) 263 return; 264 if (ftrace_set_filter(tr->ops, q, strlen(q), 0) < 0) 265 pr_err("Failed to add %s to ftrace filter\n", p); 266 else 267 ftrace_filter_param = true; 268 kfree(q); 269 } 270 xbc_node_for_each_array_value(node, "ftrace.notraces", anode, p) { 271 q = kstrdup(p, GFP_KERNEL); 272 if (!q) 273 return; 274 if (ftrace_set_notrace(tr->ops, q, strlen(q), 0) < 0) 275 pr_err("Failed to add %s to ftrace filter\n", p); 276 else 277 ftrace_filter_param = true; 278 kfree(q); 279 } 280 } 281 #else 282 #define trace_boot_set_ftrace_filter(tr, node) do {} while (0) 283 #endif 284 --- 0-DAY kernel test infrastructure Open Source Technology Center https://lists.01.org/hyperkitty/list/kbuild-all@xxxxxxxxxxxx Intel Corporation
