mm: multi-gen LRU: reuse some legacy trace events
As the legacy lru provides, the mglru needs some trace events for
debugging. Let's reuse following legacy events for the mglru.
trace_mm_vmscan_lru_isolate
trace_mm_vmscan_lru_shrink_inactive
Here's an example
mm_vmscan_lru_isolate: classzone=2 order=0 nr_requested=4096 nr_scanned=64 nr_skipped=0 nr_taken=64 lru=inactive_file
mm_vmscan_lru_shrink_inactive: nid=0 nr_scanned=64 nr_reclaimed=63 nr_dirty=0 nr_writeback=0 nr_congested=0 nr_immediate=0 nr_activate_anon=0 nr_activate_file=1 nr_ref_keep=0 nr_unmap_fail=0 priority=2 flags=RECLAIM_WB_FILE|RECLAIM_WB_ASYNC
