Once we decide to add event trace, I prefer getting more detailed information which is hard to get it via /sys/block/zram/. So, we can add trace __zs_compact as well as zs_compact with some changes.
IOW,
zs_compact trace_zs_compact_start(pool->name) __zs_compact trace_zs_compact(class, scanned_obj, freed_pages) trace_zs_compact_end(pool->name)
