libperf: Move 'leader' from tools/perf to perf_evsel::leader
Move evsel::leader to perf_evsel::leader, so we can move the group interface to libperf. Also add several evsel helpers to ease up the transition: struct evsel *evsel__leader(struct evsel *evsel); - get leader evsel bool evsel__has_leader(struct evsel *evsel, struct evsel *leader); - true if evsel has leader as leader bool evsel__is_leader(struct evsel *evsel); - true if evsel is itw own leader void evsel__set_leader(struct evsel *evsel, struct evsel *leader); - set leader for evsel Committer notes: Fix this when building with 'make BUILD_BPF_SKEL=1' tools/perf/util/bpf_counter.c - if (evsel->leader->core.nr_members > 1) { + if (evsel->core.leader->nr_members > 1) { Signed-off-by: Jiri Olsa <jolsa@kernel.org> Requested-by: Shunsuke Nakamura <nakamura.shun@fujitsu.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20210706151704.73662-4-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
