| H A D | evsel.h | 80ee8c58 Tue Apr 24 13:20:14 CDT 2018 Kan Liang <kan.liang@linux.intel.com> perf stat: Fix duplicate PMU name for interval print
PMU name is printed repeatedly for interval print, for example:
perf stat --no-merge -e 'unc_m_clockticks' -a -I 1000
# time counts unit events
1.001053069 243,702,144 unc_m_clockticks [uncore_imc_4]

2.002024821 240,750,403 unc_m_clockticks [uncore_imc_1] [uncore_imc_1]
For each print, the PMU name is unconditionally appended to the
counter->name.
Need to check the counter->name first. If the PMU name is already
appended, do nothing.
Committer notes:
Add and use perf_evsel->uniquified_name bool instead of doing the more
expensive strstr(event->name, pmu->name).
