[PATCH v1 0/3] Prefer evsel over evsel->core.idx
Posted by Ian Rogers 1 week ago
James Clark's patches fixing evsel->core.idx [1] reminded me that we
pass the int value around unnecessarily. Passing the evsel avoids
issues if the evlist is reordered but paired with sanitizers we can
also know when something is used when it shouldn't be. These patches
do some initial work reducing the use of evsel->core.idx or reducing
the API to pass evsels and not their interior index.

Ian Rogers (3):
  perf stream: Use evsel rather than evsel->idx
  perf values: Use evsel rather than evsel->idx
  perf annotate: Prefer passing evsel to evsel->core.idx
