      perf tools: Suggest using -f to override perf.data file ownership message · 071266bf
      Arnaldo Carvalho de Melo authored
        # id

        # ls -la perf.data
        -rw-------. 1 acme acme 20720 Jul  8 11:35 perf.data
      
      Previously:
      
        # perf report
        file perf.data not owned by current user or root
      
      Now:
      
        # perf report
        File perf.data not owned by current user or root (use -f to override)
