Hi Harsh and Mulyadi, Thanks a lot for your reply. Just another question, in the slabtop output, I see that we have kmalloc-64 and kmalloc-96 cache, when these caches increase their size, is it calculated in the "cache" of the "free" command or in "used". Is it reclaimable? and count in SReclaimable or SUnreclaim of cat /proc/meminfo? I know some cache like dentry or inode cache will be calculated in "cache" of free command output and SReclaimable of cat /proc/meminfo and can be freed by "echo 3 > /proc/sys/vm/drop_caches" but not sure if it the same situation for kmalloc-64 and kmalloc-96 cache.

These days, eBPF is the hot stuff to try for this matter.
