    perf tools: Fix call-chain cumul hit based sub-total (fractal mode) · 1953287b
    Frederic Weisbecker authored
    The callchain fractal mode builds each new total hits in a new
    branch of profiling by using the parent's hits of the current
    branch plus the hits of the children.
    
    This is wrong, the total hits of a branch should be made of the
    sum of every children hits, we must ignore the parent hits in
    this scope.
    
    This patch also fixes another mistake with the hit counting.
    
    Now the rates are correct.
