| |
When AGGR_THREAD is active, it aggregates the values for each thread. Previously it used cpu map index which is invalid for AGGR_THREAD so it had to use separate runtime stats with index 0.
But it can just use the rt_stat with thread_map_index. Rename the first_shadow_map_idx() and make it return the thread index.
