perf record: Correct the help info of option "--no-bpf-event"
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") Signed-off-by: Wei Li <liwei391@huawei.com> Acked-by: Song Liu <songliubraving@fb.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Hanjun Guo <guohanjun@huawei.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Li Bin <huawei.libin@huawei.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lore.kernel.org/lkml/20200819031947.12115-1-liwei391@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
