Yes, I want to get the duration of shrink lru and slab (including shrink_active_list()/shrink_inactive_list()/shrinker->count_objects()/shrinker->scan_objects()),and then calculate the memory recycling rate.

Build error has been fixed in v2 patch, changes log: v3: Swap the positions of 'nid' and 'freeable' to prevent the hole in the trace event. v2: Modify trace_mm_vmscan_lru_shrink_inactive() in evict_folios() at the same time.
