    perf maps: Remove rb_node from struct map · ff583dc4
    Ian Rogers authored
    struct map is reference counted, having it also be a node in an
    red-black tree complicates the reference counting. Switch to having a
    map_rb_node which is a red-block tree node but points at the reference
    counted struct map. This reference is responsible for a single reference
    count.
    
    Committer notes:
    
    Fixed up tools/perf/util/unwind-libunwind-local.c to use map_rb_node as
    well.
