The main reasons for adding static tracepoints are:
1. To subdivide the time spent in the shrinker->count_objects() and
shrinker->scan_objects() functions within the do_shrink_slab function. Using
BPF kprobe, we can only track the time spent in the

It would be really helpful to have more details on why we need those
trace points. It is my understanding that you would like to have a more
fine grained numbers for the time duration of different parts of the
reclaim process. I can imagine this could be

When the system memory is low, kswapd reclaims the memory. The key steps
of memory reclamation include
1.shrink_lruvec
* shrink_active_list, moves folios from the active LRU to the inactive LRU
* shrink_inactive_list, shrink lru from inactive LRU list
