  perf bench sched-messaging: Drop barf() (2014-06-19 16:13:17 -0300)

perf/core improvements and fixes:

User visible:

. Add --repeat global option to 'perf bench' to be used in benchmarks
  such as the existing 'futex' one, that was modified to use it instead
  of a local option. (Davidlohr Bueso)

. Fix fd -> pathname resolution in 'trace', be it using /proc or
  a vfs_getname probe point. (Arnaldo Carvalho de Melo)

. Add suggestion of how to set perf_event_paranoid sysctl, to help
  non-root users trying tools like 'trace' to get a working environment.
  (Arnaldo Carvalho de Melo)


. Fix memory leak in the 'sched-messaging' perf bench test. (Davidlohr Bueso)

. The -o and -n 'perf bench mem' options are mutually exclusive, emit error
  when both are specified. (Davidlohr Bueso)

. Fix scrollbar refresh row index in the ui browser, problem exposed now
  that headers will be added and will be allowed to be switched on/off.
  (Jiri Olsa)


. Remove needless reassignments in 'trace' (Arnaldo Carvalho de Melo)

. Cache the is_exit syscall test in 'trace) (Arnaldo Carvalho de Melo)

. No need to reimplement err() in 'perf bench sched-messaging', drop barf().
  (Davidlohr Bueso).

. Remove ev_name argument from perf_evsel__hists_browse, can be obtained
  from the other parameters. (Jiri Olsa)
