    perf report: Left align dynamic entries in hierarchy · cb1fab91
    Namhyung Kim authored
    The dynamic entries are right-aligned unlike other entries since it
    usually has numeric value.  But for the hierarchy mode, left alignment
    is more appropriate IMHO.  Also trim spaces on the left so that we can
    easily identify the hierarchy.
    
    Before:
    
      $ perf report --hierarchy -i perf.data.kmem -s gfp_flags,ptr,bytes_req --stdio -g none
      ...
      #
      #       Overhead                                        gfp_flags /                ptr /          bytes_req
      # ..............  .................................................................................................
      #
          91.67%                   GFP_ATOMIC|GFP_NOWARN|GFP_NOMEMALLOC
             37.50%        0xffff8803f7669400
                37.50%                       448
              8.33%        0xffff8803f766be00
                 8.33%                        96
              4.17%        0xffff8800d156dc00
                 4.17%                       704
    
    After:
    
      #       Overhead  gfp_flags / ptr / bytes_req
      # ..............  ....................................
      #
          91.67%        GFP_ATOMIC|GFP_NOWARN|GFP_NOMEMALLOC
             37.50%        0xffff8803f7669400
                37.50%        448
              8.33%        0xffff8803f766be00
                 8.33%        96
              4.17%        0xffff8800d156dc00
                 4.17%        704
