      Jiri Olsa authored
      Adding period as a default output column in script command fo hardware,
      software and raw events.
      
      If PERF_SAMPLE_PERIOD sample type is defined in perf.data, following
      will be displayed in perf script output:
      
        $ perf script
                    ls  8034 57477.887209:     250000 task-clock:  ffffffff81361d72 memset ([kernel.kallsyms])
                    ls  8034 57477.887464:     250000 task-clock:  ffffffff816f6d92 _raw_spin_unlock_irqrestore ([kernel.kallsyms])

      Adding period data column to be displayed in perf script.  It's possible
      to get period values using -f option, like:

      perf evsel: No need to drag util/cgroup.h · f14d5707
      Arnaldo Carvalho de Melo authored
      The only thing we need is a forward declaration for 'struct cgroup_sel',
      that is inside 'struct perf_evsel'.
      
      Include cgroup.h instead on the tools that support cgroups.

      perf evlist: Add missing 'struct option' forward declaration · 724ce97e
      Arnaldo Carvalho de Melo authored
      It was being found, by chance, because evsel.h needlessly includes
      util/cgroup.h, which will be sorted out in a following patch.

      perf evsel: Move exit stuff from __delete to __exit · 597e48c1
      Arnaldo Carvalho de Melo authored
      So that when an evsel is embedded into other struct it can free up
      resources calling perf_evsel__exit().

      kprobes/x86: Remove stale ARCH_SUPPORTS_KPROBES_ON_FTRACE define · 691286b5
      Anton Blanchard authored
      Commit e7dbfe34 ("kprobes/x86: Move ftrace-based kprobe code
      into kprobes-ftrace.c") switched from using
      ARCH_SUPPORTS_KPROBES_ON_FTRACE to CONFIG_KPROBES_ON_FTRACE but
      missed removing the define.
