Subject: [PATCH v3 0/2] Fixes from evsel__group_pmu_name asan error
evsel__group_pmu_name triggered an asan error as a list_head was cast
to an evsel, when it was the head, and the accessed as if it were a
full evsel. Further investigation showed problematic list iteration
for evsel__group_pmu_name whilst the list was being sorted so switch
to pre-computation.
v3: Rebase on perf-tools-next (branch getting ready for 6.5) rather
than perf-tools (fixes for 6.4).
v2: Address review comments/feedback from Adrian Hunter
<adrian.hunter@...el.com>.
