Currently the test skips with an error because == only works in bash:
$ ./perf test 91 -v
Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
91: perf stat --bpf-counters test :
--- start ---
test child forked, pid 44586
./tests/shell/stat_bpf_counters.sh: 26: [: -v: unexpected operator
test child finished with -2
---- end ----
perf stat --bpf-counters test: Skip
Changing == to = does the same thing, but doesn't result in an error:
./perf test 91 -v
Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
91: perf stat --bpf-counters test :
--- start ---
test child forked, pid 45833
Skipping: --bpf-counters not supported
Error: unknown option `bpf-counters'
[...]
test child finished with -2
---- end ----
perf stat --bpf-counters test: Skip

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.
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.
