perf test: Fix subtest number when showing results
Perf test 40 for example has several subtests numbered 1-4 when displaying the start of the subtest. When the subtest results are displayed the subtests are numbered 0-3. Use this command to generate trace output: [root@s35lp76 perf]# ./perf test -Fv 40 2>/tmp/bpf1 Fix this by adjusting the subtest number when show the subtest result. Output before: [root@s35lp76 perf]# egrep '(^40\.[0-4]| subtest [0-4]:)' /tmp/bpf1 40.1: Basic BPF filtering : BPF filter subtest 0: Ok 40.2: BPF pinning : BPF filter subtest 1: Ok 40.3: BPF prologue generation : BPF filter subtest 2: Ok 40.4: BPF relocation checker : BPF filter subtest 3: Ok [root@s35lp76 perf]# Output after: root@s35lp76 ~]# egrep '(^40\.[0-4]| subtest [0-4]:)' /tmp/bpf1 40.1: Basic BPF filtering : BPF filter subtest 1: Ok 40.2: BPF pinning : BPF filter subtest 2: Ok 40.3: BPF prologue generation : BPF filter subtest 3: Ok 40.4: BPF relocation checker : BPF filter subtest 4: Ok [root@s35lp76 ~]# Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Reviewed-by: Hendrik Brueckner <brueckner@linux.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Link: http://lkml.kernel.org/r/20180724134858.100644-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
