Hi Andrew, After merging the akpm-current tree, today's linux-next build (native perf) failed like this: bench/numa.c: In function 'bind_to_node': bench/numa.c:301:21: error: 'NUMA_NO_NODE' undeclared (first use in this function); did you mean 'NUMA_NUM_NODES'? if (target_node == NUMA_NO_NODE) { ^~~~~~~~~~~~ NUMA_NUM_NODES bench/numa.c:301:21: note: each undeclared identifier is reported only once for each function it appears in bench/numa.c: In function 'bind_to_memnode': bench/numa.c:342:14: error: 'NUMA_NO_NODE' undeclared (first use in this function); did you mean 'NUMA_NUM_NODES'? if (node == NUMA_NO_NODE) ^~~~~~~~~~~~ NUMA_NUM_NODES bench/numa.c: In function 'init_thread_data': bench/numa.c:1366:19: error: 'NUMA_NO_NODE' undeclared (first use in this function); did you mean 'NUMA_NUM_NODES'? td->bind_node = NUMA_NO_NODE; ^~~~~~~~~~~~ NUMA_NUM_NODES Caused by commit 3856193d8452 ("tools/: replace open encodings for NUMA_NO_NODE") [BTW, I did not write that patch, just added fixes last time] [BTW 2, there are lots of cc's that probably no longer apply since this was split form the previous patch] I have applied the following fix patch: From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Date: Tue, 8 Jan 2019 13:08:32 +1100 Subject: [PATCH] tools/: fix for replace open encodings for NUMA_NO_NODE Signed-off-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> --- tools/perf/bench/numa.c | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/perf/bench/numa.c b/tools/perf/bench/numa.c index e0ad5f1de226..98ad783efc69 100644 --- a/tools/perf/bench/numa.c +++ b/tools/perf/bench/numa.c @@ -34,6 +34,7 @@ #include <sys/types.h> #include <linux/kernel.h> #include <linux/time64.h> +#include <linux/numa.h> #include <numa.h> #include <numaif.h> -- 2.20.1 -- Cheers, Stephen Rothwell
