      cgroup: define controller file conventions · 6abc8ca1
      Tejun Heo 提交于
      Traditionally, each cgroup controller implemented whatever interface
      it wanted leading to interfaces which are widely inconsistent.
      Examining the requirements of the controllers readily yield that there
      are only a few control schemes shared among all.
      
      Two major controllers already had to implement new interface for the
      unified hierarchy due to significant structural changes.  Let's take
      the chance to establish common conventions throughout all controllers.
      
      This patch defines CGROUP_WEIGHT_MIN/DFL/MAX to be used on all weight
      based control knobs and documents the conventions that controllers
      should follow on the unified hierarchy.  Except for io.weight knob,
      all existing unified hierarchy knobs are already compliant.  A
      follow-up patch will update io.weight.
      
      v2: Added descriptions of min, low and high knobs.

       "This tree includes an x86 PMU scheduling fix, but most changes are
        late breaking tooling fixes and updates:
      
        User visible fixes:
      
         - Create config.detected into OUTPUT directory, fixing parallel
           builds sharing the same source directory (Aaro Kiskinen)
      
         - Allow to specify custom linker command, fixing some MIPS64 builds.
           (Aaro Kiskinen)
      
         - Fix to show proper convergence stats in 'perf bench numa' (Srikar
           Dronamraju)
      
        User visible changes:
      
         - Validate syscall list passed via -e argument to 'perf trace'.
           (Arnaldo Carvalho de Melo)
      
         - Introduce 'perf stat --per-thread' (Jiri Olsa)
      
         - Check access permission for --kallsyms and --vmlinux (Li Zhang)
      
         - Move toggling event logic from 'perf top' and into hists browser,
           allowing freeze/unfreeze with event lists with more than one entry
           (Namhyung Kim)
      
         - Add missing newlines when dumping PERF_RECORD_FINISHED_ROUND and
           showing the Aggregated stats in 'perf report -D' (Adrian Hunter)
      
        Infrastructure fixes:
      
         - Add missing break for PERF_RECORD_ITRACE_START, which caused those
           events samples to be parsed as well as PERF_RECORD_LOST_SAMPLES.
           ITRACE_START only appears when Intel PT or BTS are present, so..
           (Jiri Olsa)
      
         - Call the perf_session destructor when bailing out in the inject,
           kmem, report, kvm and mem tools (Taeung Song)

         - Reference count the cpu_map and thread_map classes (Jiri Olsa)

           generalization of some 'perf stat' functions that previously were
           accessing private static evlist variable (Jiri Olsa)
      
         - Delete an unnecessary check before the calling free_event_desc()
           (Markus Elfring)
      
         - Allow auxtrace data alignment (Adrian Hunter)

           info per entry, for ongoing 'perf stat --per-thread' work (Jiri
