When the expected sample count in the condition changed, the message needs to be changed too, otherwise we'll get: 0x1001f2091d8: mmap mask[0]: BPF filter result incorrect, expected 56, got 56 samples Fixes: 4b04e0decd2518e5 ("perf test: Fix basic bpf filtering test") Signed-off-by: Michael Petlan <mpetlan@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Sumanth Korikkar <sumanthk@linux.ibm.com> Link: https //lore.kernel.org/r/20210805160611.5542-1-mpetlan@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Chen Jun <chenjun102@huawei.com> Acked-by: Weilong Chen <chenweilong@huawei.com> Signed-off-by: Chen Jun <chenjun102@huawei.com> --- tools/perf/tests/bpf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/tests/bpf.c b/tools/perf/tests/bpf.c index 8345ff4acedf..e5832b74a845 100644 --- a/tools/perf/tests/bpf.c +++ b/tools/perf/tests/bpf.c @@ -199,7 +199,7 @@ static int do_test(struct bpf_object *obj, int (*func)(void), } if (count != expect * evlist->core.nr_entries) { - pr_debug("BPF filter result incorrect, expected %d, got %d samples\n", expect, count); + pr_debug("BPF filter result incorrect, expected %d, got %d samples\n", expect * evlist->core.nr_entries, count); goto out_delete_evlist; } -- 2.20.1
