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
