    Subject[PATCH V7 5/8] perf/tools: Add system error and not in transaction branch types
    Date
    This updates the perf tool with generic branch type classification with two
    new branch types i.e system error (PERF_BR_SERROR) and not in transaction
    (PERF_BR_NO_TX) which got updated earlier in the kernel. This also updates
    corresponding branch type strings in branch_type_name().
