perf evlist: Add perf_evlist__id2evsel_strict() (dddcf6ab) · Commits · 戴 / test

perf_evlist__id2evsel_strict() is the same as perf_evlist__id2evsel() except that it ensures that the id must match. This will be used by perf inject to find a specific evsel that is to be deleted, hence the need to match exactly. Signed-off-by:
