    perf tools: Experiment with cppcheck · 18ef15c6
    Arnaldo Carvalho de Melo authored
    Experimenting a bit using cppcheck[1], a static checker brought to my
    attention by Colin, reducing the scope of some variables, reducing the
    line of source code lines in the process:
    
      $ cppcheck --enable=style tools/perf/util/thread.c
      Checking tools/perf/util/thread.c...
      [tools/perf/util/thread.c:17]: (style) The scope of the variable 'leader' can be reduced.
      [tools/perf/util/thread.c:133]: (style) The scope of the variable 'err' can be reduced.
      [tools/perf/util/thread.c:273]: (style) The scope of the variable 'err' can be reduced.
    
    Will continue later, but these are already useful, keep them.
