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 :

40.4: BPF relocation checker :
BPF filter subtest 4: Ok
