From: Wei Li <liwei391@xxxxxxxxxx>
commit a060c1f12b525ba828f871eff3127dabf8daa1e6 upstream.
The help info of option "--no-bpf-event" is wrongly described as "record
bpf events", correct it.
Committer testing:
$ perf record -h bpf
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
--clang-opt <clang options>
options passed to clang when compiling BPF scriptlets
--clang-path <clang path>
clang binary to use for compiling BPF scriptlets
--no-bpf-event do not record bpf events
$
Fixes: 71184c6ab7e6 ("perf record: Replace option --bpf-event with --no-bpf-event")
