touching anything in the other perf_session members.\n\nOther optimizations, such as calculating the maximum lenght of a symbol\nname present in an hists instance will be possible as we add them,\navoiding a re-traversal just for finding that information.\n\nThe rationale for the name \"hists\" to replace \"event_stat_id\" is that we\nmay have multiple sets of hists for the same event_stat id, as, for\ninstance, the \u0027perf diff\u0027 tool has, so event stat id is not what\ncharacterizes what this struct and the functions that manipulate it do.\n\nCc: Eric B Munson
