[ Upstream commit 9ef0112442 ]
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

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
