2009-08-09perf tools: Fix multi-counter stat bug caused by incorrect reading of ↵Peter Zijlstra
perf.data file header Brice Goglin reported that only the first result from a multi-counter perf record --stat run is accurate, the rest looks bogus. A silly mistake made us re-read the first attribute for every recorded attribute.
