    Subject[PATCH 21/25] perf tools: Add perf_evlist__id2evsel_strict()
    Date
    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.
